A sample of n2o gas has a density of 3.10 g/l at 298 k.what must be the pressure of the gas (in mmhg)?
P=___mmHg

Answers

Answer 1

The pressure of N2O gas at a density of 3.10 g/L and a temperature of 298 K is 751 mmHg. To calculate the pressure of the N2O gas at a given density and temperature, we can use the ideal gas law: PV = nRT.

We know that the density of the gas is 3.10 g/L, and the temperature is 298 K. To find the pressure, we can assume that the volume of the gas is 1 L, and solve for pressure. where P is the pressure of the gas, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

The density of a gas can be converted to moles using the formula:

Density = m/V

m = Density*V

Now we can use the ideal gas law to calculate the pressure:

P = (mRT)/V

R is the ideal gas constant = 0.0821 L atm K^-1 mol^-1

P = (3.10g0.0821 L atm K^-1 mol^-1298 K)/1 L

P = 751 mmHg

A 50.0 mLmL sample of 0.200 MM sodium hydroxide is titrated with 0.200 MM nitric acid. Calculate the pHpH in the titration after the addition of 60.0 mLmL of 0.200 MHNO3MHNO3 .

Answers

A rough estimate of the excess pH of the solution is 1.74.

The answer to the question is that the concentration of NaOH is 0.2 M.

The question also states that the concentration of HNO3 is equal to that of NaOH, which is 0.2 M.

The volumes of sodium hydroxide and nitric acid that are provided to us are 50 mL and 60 mL, respectively. This implies that adding the two will result in the final volume.

= 50 plus 60 equals 110, or 0.11 liters

We know that there is a neutralizing reaction between NaOH and HNO3 based on theory. Then, as a means of answering the question, we record the aforementioned equation.

OH⁻ + H⁺ ---> H₂O

Finally, we apply logarithm to get our final answer

pH = - log [ H⁺ ]

pH = - log [0.01818]

how many liters of water can be made from 55 grams of oxygen gas and an excess of hydrogen at a pressure of 12.4 atm

Answers

At a pressure of 12.4 atm and a temperature of 850 c, 8.2 liters of water can be created from 55 grams of oxygen gas and an excess of hydrogen.

first, we need the no.of moles of O2 = mass/molar mass of O2

                                                            = 55 g / 32 g/mol

                                                            = 1.72 mol

from the balanced equation of the reaction:

2H2 (g) + O2(g) → 2H2O(g)

we can see that the molar ratio between O2: H2O = 1: 2

So we can get the no.of moles of H2O = 2 * moles of O2

                                                                 = 2 * 1.72 mol

                                                                 = 3.44 mol

So by substitution by this value in the ideal gas formula:

PV = nRT

when P = 12.4 atm  & n H2O = 3.44 mol & R= 0.0821 & T = 85 + 273=358K

12.4 atm *V = 3.44 * 0.0821 * 358 = 8.15 L

∴ V ≈ 8.2 L

Similarities:

Ethanoic acid and sodium carbonate combine to form an endothermic reaction that results in fizzing as carbon dioxide is released and heat is lost to the environment, making the reaction vessel feel chilly to the touch.

Differences:

The difference between adding sodium carbonate to the solution and refrigerating ethanoic acid is that no new substance is created in the former. When the substance is taken out of the refrigerator, it is still ethanoic acid. New chemicals are created in the latter scenario.

Answers

The new volume in litres is 13.29 L.

Given,

Temperature 1 (T₁) = 298 K

Volume 1 (V₁) = 15 L

Temperature 2 (T₂) = 383 K

Pressure 1 (P₁) = 3.36 atm

Pressure 2 (P₂) = 4. atm

By Ideal Gas Equation,

P₁V₁/T₁ = P₂V₂/T₂

⇒ (3.36*15)/298 = (4.90*V₂)/383

⇒50.4/298 = 4.90V₂/383

⇒ (50.4*383) / (298*4.90) = V₂

We know that 1mole Sulpher results in the production of \ bigtri angle up Hrxn=75.8 kJ/mol energy.

25.9 kJ of energy produced from how many grams of sulpher= 25.9 kJ / 75.8 kJ/mol = 25.9g/75.8g/mol

                                                                                                                                     =0.34 mol of sulpher

The amount of 0.34 moles of sulpher in grams= Number of moles * Molar mass 

( Molar mss of Sulpher= 32.06g'/mol)

= 0.34mols * 32.06g /mol

=10.95 g

 The amount of suplher in grams to rpoduce 25.9 kJ energy= 10.95g

Suppose that a chemist combines 231 mL of methane and 907 mL of chlorine at STP in a 2.00 L flask. The flask is then allowed to stand at 298 K. If the reaction reaches 75.9% completion, what is the total pressure in the flask

Answers

The total pressure in the flask is 1.320 times the total pressure.

What is pressure?

Pressure is an important concept in chemistry, as it affects the physical behavior of gases and solids, and the rates at which reactions occur. Pressure is a measure of the force applied to an area, typically expressed in units of atmospheres (atm), or kilopascals (kPa).

Methane :

Mole fraction of methane = (231 mL / 2.00 L) = 0.1155

Partial pressure of methane = 0.1155 * Ptotal

Chlorine:

Mole fraction of chlorine = (907 mL / 2.00 L) = 0.4535

Partial pressure of chlorine = 0.4535 * Ptotal

Products:

Mole fraction of products = (75.9% com) = 0.759

Partial pressure of products = 0.759 * Ptotal

Total pressure = 0.1155*Ptotal + 0.4535*Ptotal + 0.759*Ptotal = 1.320*Ptotal

Answers

D. a) propanoyl chloride with (1) AlCl3 and (2) H2O b) Br2 / heat or light.

What is a reagent?

A reagent is a substance that is used in a chemical reaction to detect, measure, examine, or produce other substances. Reagents are used in many different industries, including pharmaceuticals, environmental testing, and materials science. Reagents can be in the form of a solid, liquid, or gas, and are generally made from a combination of elements, compounds, or mixtures.

a) The reaction of propanoyl chloride with AlCl3 and H2O can be represented as follows:

AlCl3 + H2O + Propanoyl Chloride → Al(OH)3 + HCl + Propanoic Acid

This reaction involves substitution of the chlorine atom in the propanoyl chloride molecule with a hydroxide ion from the AlCl3/H2O mixture.

b) Br2 / heat or light cannot be used to react with propanoyl chloride, as this reaction would require the breaking of the carbon-chlorine bond. This is not possible using Br2 / heat or light.

What are the 3 types of elements?

Answers

The three types of elements are metals, non-metals as well as metalloids, there are placed in a periodic table.

In a periodic table, metals are placed in s-block and d-block. While non-metals as well as metalloids are placed in p-block. Metals are generally lustrous, malleable as well ductile in nature and are usually hard in nature while non-metals lack these properties. Metalloids are the elements whose chemical as well as physical properties lies between both metals and non-metals. Examples of metals are sodium and potassium. Examples of non-metals are carbon and phosphorus while examples of metalloids are silicon and germanium.

How long will it take Caroline to travel 45 miles if she is traveling 37mph (miles per hour)?

Answers

In the given question,It will take Caroline 1.2 hours  to travel 45 miles if she is traveling 37 mph (miles per hour).

As we know the velocity formula:

v = d/t

Where

V is velocity, d is distance and t is time.

as given in the question

distance = 45 miles

velocity = 37 mph

To find time t,

put the values in the formula:

t = d/v

t = 45/37

t = 1.2 hours

It will take Caroline 1.2 hours  to travel 45 miles if she is traveling 37 mph (miles per hour).

In an atom that has lost an electron, the place vacated by the free electron is referred to as a(n)

Answers

The space left by the free electron in an atom after it has lost one electron is known as a hole.

The term "free electron" refers to an electron that has broken loose from its "parent" atom and is now free to move about the material at random. A vacancy, also known as a hole, is created in the atom when a bonded electron in a lattice atom breaks free. The number of electrons in an atom's valence shell, or n shell in this example, has a significant impact on the electrical properties of the element that the atom represents. The least force of attraction is felt by the electrons in the valence shell since they are the furthest from their nucleus.
