Using C2H4 + 3 O2 -> 2 CO2 + 2 H2O.
What is the limiting reactant for this equation based on the previous question?

Answers

Answer 1

There is no limiting reactant because both reactants produce the same amount of products indicating that neither reactant is in excess and both are fully consumed in the reaction.

What is a limiting reactant?

The limiting reagent is described as  the reactant that is completely used up in a reaction, and thus determines when the reaction stops.

calculating the number of moles of each reactant of the equation:

C2H4 + 3 O2 -> 2 CO2 + 2 H2O.

Moles of C2H4: not given, assume 1 mole

Moles of O2: 3 moles (given in the equation)

Moles of CO2 produced by 1 mole of C2H4: 2 moles (from the balanced equation)

Moles of H2O produced by 1 mole of C2H4: 2 moles (from the balanced equation)

Moles of CO2 produced by 3 moles of O2: 2 x 3/3 = 2 moles (from the balanced equation)

Moles of H2O produced by 3 moles of O2: 2 x 3/3 = 2 moles (from the balanced equation)

In conclusion, both reactants produce the same amount of products (2 moles of CO2 and 2 moles of H2O).

match the problems that arise when a particular situation is present when running a spectrum of a neat liquid:

Answers

The problem that arises when running a spectrum of a neat liquid is that it can be difficult to distinguish the peaks in the spectrum due to the broadening of the baseline.

This is because the baseline broadening is caused by the interaction of the solvent molecules with the solute molecules, which is difficult to avoid. To reduce the baseline broadening, it is necessary to reduce the solvent concentration or use a denser solvent. In addition, it is also important to ensure that the sample is well-mixed, since inhomogeneity in the sample can lead to peak broadening. It is also important to reduce noise in the spectra, since this can lead to peak broadening or obscuring of the peaks. Finally, it is important to carefully choose the range of wavelengths to be measured, since if the range is too wide, then the baseline broadening may obscure the peaks.

In conclusion, the problems that arise when running a spectrum of a neat liquid include baseline broadening, inhomogeneity in the sample, noise in the spectra, and a too wide range of wavelengths being measured. To reduce these issues, it is important to reduce the solvent concentration or use a denser solvent, ensure that the sample is well-mixed, reduce noise in the spectra, and carefully choose the range of wavelengths to be measured.

select all ions that are produced when nh4cl is dissolved in water. group of answer choices hcl nh nh3 nh4 cl-

Answers

When NH4Cl is dissolved in water, the following ions are produced are H+, Cl-, NH3, and NH4+.


When NH4Cl is dissolved in water, the ions that are produced are  H+, Cl-, NH3, and NH4+. An ion is an electrically charged atom or molecule. When a neutral atom or molecule gains or loses electrons, it acquires an electric charge and becomes an ion.

Conventionally, the charge of an electron is thought to be negative; this charge is equal to and opposite to the charge of a proton, which is thought to be positive. Because the total number of electrons in an ion is more than the total number of protons, the net charge of an ion is not zero.

A negatively charged ion called an anion has more electrons than protons compared to a positively charged ion called a cation. Electrostatic force causes opposite electric charges to be drawn towards one another, causing cations and anions to attract one another and easily form ionic compounds.

The ammonium ion, NH4+, is generated when ammonia (NH3) is combined with a hydrogen ion (H+), which results in the formation of NH4+ ions. When NH4Cl dissolves in water, the NH4Cl dissociates into its component ions, NH4+ and Cl-.

As a result, the answer is H+, Cl-, NH3, and NH4+.

A tube is the term used to describe the straw-like organ utilized by both plants and animals to consume food and water or to eliminate waste.

What is tube?

A hollow, cylindrical structure that is often present in living things is referred to as a tube. Many biological structures, such as blood veins, intestines, respiratory tracts, and the reproductive system, contain tubes. Many biological functions, including the passage of nutrients, the exchange of gases, and the removal of waste materials, depend on tubes.

These tubes are referred to as xylem and phloem in plants. While the phloem moves sugars and other nutrients from the leaves to other parts of the plant, the xylem is in charge of moving water and minerals from the roots to the rest of the plant.

Animals have many species-specific tube-like organs in charge of intake and waste elimination. Mammals, for instance, have a sophisticated digestive system that consists of the anus, esophagus, stomach, and intestines. Together, these organs help the body digest food, extract nutrients, and get rid of waste.

A sample of a gas occupies 460 ML at 70.0 degree celcius and 1.00 atmosphere. At what temperature would the gas occupy 650 ML at the same pressure

Answers

approximately 210.92°C to occupy a volume of 650 mL at 1.00 atm pressure.

At the same pressure of 1.00 atmosphere, the gas would occupy 650 mL at a temperature of approximately 212.33 degrees Celsius.

To solve this problem, we use combined gas law equation:

(P₁ × V₁) / T₁ = (P₂ × V₂) / T₂

Where:

P₁ = Initial pressure

V₁ = Initial volume

T = Initial temperature

P₂ = Final pressure (same as initial pressure)

V₂ = Final volume

T₂ = Final temperature

Given:

P₁ = P₂ = 1.00 atm (pressure remains constant)

V₁ = 460 mL

T₁ = 70.0 degrees Celsius (converted to Kelvin)

V₂ = 650 mL

First, let's convert the initial temperature to Kelvin:

T₁(K) = T₁(°C) + 273.15

T₁(K) = 70.0 + 273.15

T₁(K) = 343.15 K

Now we plug in the values into the combined gas law equation and solve for T₂

(1.00 × 460) / 343.15 = (1.00 × 650) / T₂

Simplifying the equation:

460 / 343.15 = 650 / T₂

Cross-multiplying and solving for T₂

460 × T₂ = 650 × 343.15

T₂ = (650 × 343.15) / 460

Calculating T₂

T₂ = 485.48 K

Now, let's convert the final temperature from Kelvin back to degrees Celsius:

T₂(°C) = T₂(K) - 273.15

T₂(°C) = 485.48 - 273.15

T₂(°C) = 212.33°C

Therefore, at the same pressure of 1.00 atmosphere, the gas occupied 650 mL at a temperature of approximately 212.33 degrees Celsius.

Dissolving 7.51 g of CaCl2 in enough water to make 332 mL of solution causes the temperature of the solution to increase by 3.25 oC. Assume the specific heat of the solution and density of the solution are the same as water′s (about 4.18 J/goC and 1.00 g/cm3, respectively) Calculate ΔH per mole of CaCl2 (in kJ) for the reaction under the above conditions.

Answers

Answer:

65.72 kJ/mol

Explanation:

The temperature change, ΔT, can be used to calculate the amount of heat absorbed by the solution:

q = CmΔT

where q is the heat absorbed, C is the specific heat capacity of water (4.18 J/goC), m is the mass of the solution, and ΔT is the temperature change.

The mass of the solution can be calculated using its density:

m = Vd

where V is the volume of the solution (332 mL = 0.332 L), and d is the density of water (1.00 g/cm3).

m = 0.332 L x 1.00 g/cm3 = 332 g

The amount of heat absorbed, q, can now be calculated:

q = CmΔT = (4.18 J/goC) x (332 g) x (3.25 oC) = 4447 J

This amount of heat is absorbed by the dissolution of 7.51 g of CaCl2. To calculate the enthalpy change per mole of CaCl2, we need to convert grams to moles:

moles of CaCl2 = 7.51 g / 110.98 g/mol = 0.0676 mol

Therefore, the enthalpy change per mole of CaCl2 is:

ΔH/mol = q / moles of CaCl2 = 4447 J / 0.0676 mol = 65720 J/mol = 65.72 kJ/mol

So the enthalpy change per mole of CaCl2 is 65.72 kJ/mol.

Given that 4 NH3 + 5 O2 → 4 NO + 6 H2O, if 3.00 mol NH3 were made to react with excess of oxygen gas, the amount of H2O formed would be

Answers

Answer:

x mol H2O = 4.50 mol H2O

Step-by-step explanation:

From the balanced equation, we can see that for every 4 moles of NH3 that react, 6 moles of H2O are formed. Therefore, we can use a proportion to find the amount of H2O that would be formed if 3.00 mol of NH3 reacted:

4 mol NH3 : 6 mol H2O = 3.00 mol NH3 : x mol H2O

Solving for x, we get:

x mol H2O = (6 mol H2O / 4 mol NH3) * 3.00 mol NH3
x mol H2O = 4.50 mol H2O

Therefore, if 3.00 mol of NH3 were made to react with excess oxygen gas, 4.50 mol of H2O would be formed.

Calculate number of atoms in 30g Na

Answers

Answer:

The molar mass of Na is 22.99 g/mol (rounded to two decimal places).

To calculate the number of atoms in 30 g Na, we first need to convert the mass to moles using the molar mass:

moles of Na = 30 g / 22.99 g/mol = 1.304 mol (rounded to three decimal places)

Next, we can use Avogadro's number, which tells us the number of particles (atoms, molecules, etc.) in one mole of a substance. Avogadro's number is approximately 6.02 x 10^23 particles per mole.

So, to find the number of atoms in 1.304 moles of Na:

number of atoms = 1.304 mol x (6.02 x 10^23 atoms/mol) = 7.854 x 10^23 atoms

Therefore, there are approximately 7.854 x 10^23 atoms in 30 g Na.

Answers

Answer:

50.00 cm³

Explanation:

Relevant formula:

n = V × c

n = number of moles (mol)

V = volume (dm³)

c = concentration (mol/dm³)

1. Work out moles of KOH

V = 50cm³ = 0.05dm³

Note: remember to convert to the right units (1 dm³ = 1000cm³)

c = 0.2

n = 0.05 × 0.2

n = 0.01

2. Use balanced reaction equation to find the moles of H2SO4

c = 0.1

H2SO4 + 2KOH --> K2SO4 + 2H2O

Ratio of KOH to H2SO4:

2 : 1 (--> 1 is ½ of 2)

If we have 0.01 moles of KOH therefore:

0.01 : x

x = 0.005 (i.e. ½ of 0.01)

3. Calculate volume of H2SO4

n = V × c

0.005 = V × 0.1

V = 0.005 ÷ 0.1

V = 0.05

This reaction will take 0.05 dm³ of H2SO4, or 50 cm³

2. To determine the order of reaction with respect to the NaOH (Y in the example), we must take the derivative of the rate law equation with respect to Y, which gives us the expression:

[tex]-d[Y]/dt = k[X]^x[Y]^y.[/tex]

This equation tells us that the order of reaction with respect to Y is y.

3. To determine k, we must take the rate law equation, plug in the appropriate values, and solve for k. The equation we are solving is:

[tex]-d[X]/dt = k[X]^x[Y]^y.[/tex]

4. The overall, modified rate law with the appropriate values for X, Y, and k inserted into the equation is:

[tex]-d[X]/dt = k[X]^x[Y]^y.[/tex]

5. Solving the rate law, we get:

[tex]k = (-d[X]/dt) / (71.8^x[0.02803]^y).[/tex]

6. To find the concentration of crystal violet dye solution in each concentration of NaOH, we must use the equation:

[tex][X] = [X]0 + kt,[/tex]

where [X]0 is the initial concentration of crystal violet dye solution, k is the rate constant, and t is the time elapsed. Plugging in the appropriate values for each trial will give us the desired concentration of crystal violet dye solution for each concentration of NaOH.

if we had 79.3 grams of xe, would we expect a volume that is greater than or less than that obtained with neon

Answers

If we had 79.3 grams of Xe, we would expect a volume that is greater than that obtained with neon.

The volume of a gas depends on the number of moles of gas, temperature, and pressure. The gas's molar mass is not a factor in determining the volume of the gas. The ideal gas law, PV = nRT, can be used to find the volume of a gas.

PV = nRT can be rearranged as V = (nRT)/P, where V is the volume of the gas, n is the number of moles of the gas, R is the gas constant, T is the temperature, and P is the pressure of the gas. We can see that the volume of the gas is directly proportional to the number of moles of the gas. Therefore, a greater number of moles of gas would correspond to a larger volume.

If we had 79.3 grams of Xe, we can use the molar mass of Xe to find the number of moles of Xe. The molar mass of Xe is 131.29 g/mol.

Therefore, the number of moles of Xe would be:79.3 g Xe / 131.29 g/mol = 0.604 moles of Xe

On the other hand, if we had neon, which has a molar mass of 20.18 g/mol, the number of moles of neon would be 79.3g Ne / 20.18 g/mol = 3.93 moles of Ne

Therefore, we can see that the number of moles of neon is greater than the number of moles of Xe. Therefore, we would expect a greater volume of neon compared to Xe.

Answers

The conjugate base of a neutral acid that donates a proton will have a charge of -1.

When a neutral acid donates a proton, it is undergoing a process called deprotonation, meaning it has lost a proton from its molecular structure. In this reaction, the neutral acid becomes an anion (negatively charged ion) and the proton is picked up by the base, which is then referred to as the conjugate base of the acid. The conjugate base will have a charge of -1 because it now has one extra electron relative to the original neutral acid.
To illustrate this reaction, consider acetic acid (CH3COOH) donating a proton to a base. When the acid donates a proton, it becomes an anion, CH3COO-, and the base, which has gained a proton, is the conjugate base and has a charge of -1.
In summary, when a neutral acid donates a proton, the conjugate base will have a charge of -1.

The equilibrium constant for the reaction at 25 °C is 4.749.

ΔG for the reaction at body temperature is -4.899 kJ/mol.

How ot calculate equilibrium constant and change in free energy?

The standard free energy change (ΔG°) of the reaction is given as -3.860 kJ/mol.

At 25°C, the equilibrium constant (K'eq) can be calculated using the following equation:

ΔG° = -RTlnK'eq

where R is the gas constant (8.314 J/molK) and T is the temperature in Kelvin (25°C = 298 K).

Converting the given units of ΔG° to joules/mol:

ΔG° = -3.860 kJ/mol = -3.860 × 10³ J/mol

Substituting the values in the equation:

-3.860 × 10³ J/mol = -(8.314 J/molK) × 298 K × lnK'eq

Solving for K'eq:

lnK'eq = 14.678

K'eq = e^(14.678) = 4.749 (rounded to three significant figures)

At 37.0°C, the ΔG for the reaction can be calculated using the following equation:

ΔG = ΔG° + RTln(Q)

where R is the gas constant (8.314 J/molK), T is the temperature in Kelvin (37.0°C = 310 K), and Q is the reaction quotient.

Q = [B]/[A] = 0.45/1.7 = 0.265

Substituting the values in the equation:

ΔG = -3.860 × 10³ J/mol + (8.314 J/molK) × 310 K × ln(0.265)

ΔG = -4.899 kJ/mol (rounded to three significant figures)

i) Initiation: Chlorine molecules absorb high-energy UV radiation, which causes the chlorine bond to break homolytically, producing two chlorine radicals. This process requires energy and is endothermic.

Cl2 + energy (UV) → 2Cl•

ii) Propagation: The chlorine radical attacks a methane molecule, breaking the C-H bond and producing a methyl radical and HCl. The methyl radical then reacts with another chlorine molecule, producing another chlorine radical and chloromethane. The chlorine radical then continues to react with more methane molecules, propagating the reaction.

Cl• + CH4 → •CH3 + HCl

•CH3 + Cl2 → CH3Cl + Cl•

iii) Termination: In the termination stage, radicals combine to form products, which stops the propagation of the reaction. For example, two methyl radicals can combine to form ethane, or a chlorine radical and a methyl radical can combine to form methyl chloride.

•CH3 + •CH3 → C2H6

•CH3 + Cl• → CH3Cl

The overall reaction for the formation of chloromethane from methane and chlorine in the presence of UV light is:

CH4 + Cl2 + UV light → CH3Cl + HCl

is CF3Cl a polar or non-polar molecule?

Answers

Answer: Polar

Explanation: This is because if you look up the Lewis Dot structure of this specific molecule, it will have some net dipole moment, which makes it polar.

It can be considered that when a molecule does have some net dipole moment, it is polar.

So, yes CF3Cl is polar.

CF₃Cl, also known as chlorotrifluoromethane, is a polar molecule.

To determine the polarity of a molecule, consider the individual bond polarities and the molecular geometry.

In CF₃Cl, there is a difference in electronegativity between carbon (C) and chlorine (Cl), as well as between carbon and fluorine (F). Chlorine and fluorine are more electronegative than carbon, meaning they have a greater ability to attract electrons toward themselves.

The C-Cl bond and the C-F bonds in CF₃Cl are polar bonds due to the electronegativity difference. The Cl and F atoms pull the shared electrons towards themselves, creating partial negative charges on those atoms and partial positive charges on the carbon atom.

Answer the following questions with a true or a false. PLease help me this is due in 5 more minutes

1.Natural hazards cause a range of negative impacts on people including disruptions to daily life, damage to property, economic loss, and injury to people.

2.Natural hazards vary in their severity (the degree to which they have impacts) because of the range of magnitudes that are possible for any natural hazard event.

3.Many natural hazards cause damage to property such as buildings, roads, vehicles, bridges. They cause these damages due to the unbalanced forces that shaking, moving water, and wind place on objects. These forces cause objects to accelerate suddenly and then decelerate suddenly when they collide into objects that are at rest or that are moving in a different direction.

4. The most intense and impactful natural hazard events of the past can help predict the possible intensity and damages of future hazards.

5.It is possible to predict how likely it is that a natural hazard event will occur in the future by examining how often such events have occurred in the past.

6.Patterns in the locations of past events help us forecast future events.

7.In order to make forecasts based only on records of past events, scientists must assume that the conditions that created those hazards in the past will remain the same in the future.

Describe Natural Hazards?

Natural hazards are natural phenomena that can potentially cause harm or damage to humans, property, or the environment. These hazards are events that are caused by natural processes, such as geological, meteorological, hydrological, or biological processes. Natural hazards can range from relatively minor events, such as a small earthquake or a local flood, to catastrophic events, such as a volcanic eruption, a major earthquake, or a tsunami.

This statement is true. Natural hazards, such as earthquakes, hurricanes, floods, and wildfires, can cause a wide range of negative impacts on people and communities, including disruptions to daily life, damage to property, economic loss, and injury to people.

This statement is true. Natural hazards vary in their severity because they can occur in a range of magnitudes, from mild to extreme. The severity of a natural hazard event depends on various factors, such as the strength and duration of the event, the location and vulnerability of the affected population, and the preparedness and response capacity of the community.

This statement is true. Many natural hazards, such as earthquakes, hurricanes, and tornadoes, cause damage to property by exerting unbalanced forces on objects. These forces can cause objects to accelerate suddenly and then decelerate suddenly when they collide into objects that are at rest or that are moving in a different direction.

This statement is true. Studying the most intense and impactful natural hazard events of the past can help scientists and communities better understand the possible intensity and damages of future hazards. This information can be used to improve preparedness, response, and recovery efforts.

This statement is true. Examining the historical record of natural hazard events can help scientists and communities predict how likely it is that a similar event will occur in the future. This information can be used to assess risk and inform decision-making.

This statement is true. Patterns in the locations, frequency, and intensity of past natural hazard events can help scientists and communities forecast future events. For example, if a certain area has experienced frequent earthquakes in the past, it is more likely to experience earthquakes in the future.

This statement is false. While records of past events can provide valuable information for predicting future hazards, scientists do not assume that the conditions that created those hazards in the past will remain the same in the future. They consider a wide range of factors, such as changes in climate, land use, and population density, that may affect the occurrence and impact of natural hazards.

fill in the blank. the electron transport chain harnesses the potential energy of the molecules___, which donate electrons to proteins in the electron transport chain.

Answers

The electron transport chain harnesses the potential energy of the molecules NADH and FADH2, which donate electrons to proteins in the electron transport chain.

NADH and FADH2 are coenzymes that help transfer electrons from metabolic reactions such as glycolysis, the citric acid cycle, and fatty acid oxidation. The electrons from NADH and FADH2 are passed from one electron carrier to another until they reach the terminal electron acceptor, which is usually oxygen. As the electrons are passed along the electron transport chain, energy is released and used to produce a form of energy that cells can use, called ATP. The energy produced by the electron transport chain is used by cells to do work, such as muscle contraction, active transport, and protein synthesis. The electron transport chain is a vital process that occurs in all cells, and it is responsible for the production of ATP, which is necessary for cells to function properly.

Consider the following silica gel TLC plate of compounds A, B, and C developed in hexanes:
Consider the following silica gel TLC plate of com
a) Determine the R f values of compounds A, B, and C run on a silica gel TLC plate using hexanes as the solvent
b) Which compound, A, B, or C, is the most polar?
c) What would you expect to happen to the R f values if you used acetone instead of hexanes as the eluting solvent? (Think polarity of solvents)

Answers

The R f values for compounds A, B, and C on a silica gel TLC plate developed in hexanes would be determined by measuring the distance each compound traveled compared to the distance the solvent traveled.

a) There is a 4 cm gap between the origin and the solvent front. The Rf value for spot A is[tex]\frac{1.5}{4}= 0.375[/tex], because it travelled 1.5 cm. Due to the 3.5 cm movement of Spot B, its Rf is[tex]\frac{3.5}{4} = 0.875[/tex]. Spot C shifted 3 cm, making its Rf [tex]\frac{3}{4} = 0.75[/tex].

b)Due to its shorter travel distance than the other two compounds, compound A is the most polar. Recall that polar substances adhere to the adsorbent more readily, move less, and have a lower Rf value.

c)Hexanes is less polar than acetone as a solvent. Each of the three compounds would move more quickly if the same method were employed to elute them.The chemicals can be removed from the polar adsorbent more effectively with a more polar eluting solvent. Each compound would have a higher Rf value if acetone were used to elute the TLC plate as opposed to hexanes because each compound travels more quickly.
