In a titration experiment, a 12.5 mL sample of 1.75 x 10^-2 M Ba(OH) 2 just neutralized 14.5 mL of HNO 3 solution. Calculate the molarity of the HNO 3 solution.

Answers

The number of moles must be equal, the ratio of the molarity of each must be equal to the ratio of the volumes used.

What is experiment?

An experiment is a procedure or set of procedures used to test a hypothesis or explore a cause and effect relationship. It is a scientific method of investigation in which the investigator manipulates one or more independent variables and measures the subsequent effect on one or more dependent variables. Experiments are conducted to answer questions, test theories, and gain insight into cause-and-effect relationships.

The molarity of the HNO 3 solution can be calculated using the equation:
Molarity of HNO3 = (volume of HNO3 * molarity of Ba(OH)2) / volume of Ba(OH)2
Molarity of HNO3 = (14.5 mL * 1.75 x 10^-2 M) / 12.5 mL
Molarity of HNO3 = 1.4 x 10^-2 M
This equation works because the number of moles of HNO3 neutralized by the Ba(OH)2 must be equal to the number of moles of Ba(OH)2 used. The number of moles of each can be determined by multiplying the molarity of each by the volume used, and since the number of moles must be equal

The temperature inside a pressure cooker is 117°C. Calculate the vapor pressure of water inside the pressure cooker. What would be the temperature inside the pressure cooker if the vapor pressure of water was 2.85 atm?

Answers

The vapor pressure of water at its boiling point 100°C is 1 atm. Then the pressure at 117°C is 1.17 atm and the temperature of water at a pressure of 2.85 atm is 285°C.

What is boiling point ?

Boiling point of a substance is the temperature at which it converts from liquid state to vapor state. At this temperature the vapor pressure of water vapor is equal to the atmospheric pressure that is 1 atm .

The temperature-pressure relation is written as:

P1 /T1 = P2/ T2

Now, the pressure inside the cooker at a temperature of 117°C is calculated as:

(1 atm × 117 °C) / 100 °C = 1.17 atm.

Thus, pressure at 117 °C is 1.17 atm. Then, If the pressure is 2.85 atm, then the temperature of water inside the pressure cooker is calculated as:

(2.85 atm × 117 °C) / 1.17 = 285 °C

Therefore, the temperature at 2.85 atm is 285 °C.

when a set amount of marble chips (caco3) is added to a small amount of dilute hydrochloric acid, a reaction occurs. what should be done to decrease the rate of reaction the next time the experiment is performed

Answers

A tiny amount of weak hydrochloric acid is mixed with a quantity of marble chips (CaCO3), to decrease the rate of reaction we do decreasing the surface area of the marble chips, decreasing conc. HCL and many more.

Several ways are:-

1. Decreasing the surface area of the marble chips: By breaking the marble chips into smaller pieces, the surface area that is available for the acid to react with is reduced, slowing down the reaction.

2. Decreasing the concentration of the hydrochloric acid: By using a less concentrated solution of hydrochloric acid, the number of acid molecules available to react with the marble chips is reduced, slowing down the reaction.

3. Increasing the temperature: By performing the reaction at a lower temperature, the kinetic energy of the acid and marble chip molecules is reduced, slowing down the rate of collision between them, which slows down the reaction.

4. Using a catalyst: Addition of a catalyst to the reaction can change the reaction mechanism and decrease the activation energy needed for the reaction to occur, thus slowing down the reaction.

5. Using an inhibitor: An inhibitor is a substance that slows down the reaction by binding to the enzyme or catalytic site and preventing the substrate from binding.

It's important to note that these methods may also affect the overall yield of the reaction, so it's essential to use the appropriate method(s) for the specific experiment and goals.

Ex: Mg + 2HCl—-> MgCl₂ + H₂ If 4.48L of H₂ gas at STP is
produced in 40 sec, what is the reaction rate in mol/sec?

Answers

Answer:

The reaction rate in mol/sec is 0.005.

Explanation:

To determine the reaction rate in mol/sec, you need to first determine the number of moles of H₂ gas produced in the reaction. The volume of a gas at STP (standard temperature and pressure) is directly proportional to the number of moles of the gas, so you can use the volume of H₂ gas produced to calculate the number of moles.

At STP, 1 mole of a gas occupies a volume of 22.4 L. Therefore, the number of moles of H₂ gas produced in the reaction can be calculated as follows:

moles H₂ = 4.48 L / 22.4 L/mol = 0.2 mol

To determine the reaction rate in mol/sec, you need to divide the number of moles of H₂ gas produced by the time it took for the reaction to occur:

reaction rate (mol/sec) = 0.2 mol / 40 sec = 0.005 mol/sec

So, the reaction rate in mol/sec is 0.005.

Answers

The freezing point of the solution after you add an additional 1.34 g is -0.808°C.

What is freezing point of a solution?

A solution's freezing point is lower than the pure solvent's freezing point. This means that for freezing to happen, a solution needs to be cooled to a lower temperature than the pure solvent.

We use the equation: to determine the mass of the solution

Density = mass/volume

1.05 g/ml = mass/ 50ml

mass = 1.05×50

mass = 52.5g.

Percentage of magnesium chloride in the solution is 1.52%

Mass of magnesium chloride in the solution = 1.52 % of 52.5 g

Mass of magnesium chloride in the solution = 1.52/100×52.5

Mass of magnesium chloride in the solution = 0.798g

The following equation is used to determine depression in freezing point:

ΔTf = Freezing point of pure solution - Freezing point of solution

ΔTf = i Kf m

Freezing point of pure solution - Freezing point of solution = i Kf m

m =  m solute × 100/M solute × W solvent

Given values,

Freezing point of pure solution (water) is 0°C

i is Vant hoff factor = 2.5

A water molecule is polar because the electrons are not shared equally between the oxygen and hydrogen atoms. Oxygen is more electronegative than hydrogen, so it pulls the electrons closer to itself, creating a partial negative charge on the oxygen side of the molecule and a partial positive charge on the hydrogen side. This causes the molecule to have a dipole moment and makes the molecule polar.

What is an Empirical formula?

An empirical formula is a type of chemical formula that shows the simplest ratio of atoms in a molecule, rather than the total number of atoms. It is the simplest possible chemical formula that shows the relative numbers of each type of atom in a molecule.

This formula is determined by dividing the mass of each element by its atomic weight, and then dividing the result by the lowest of the results. The lowest result is 0.817 g/mol for carbon. This means that 2.61 g of carbon is equivalent to 3.17 moles of carbon. Thus, the ratio of elements in the compound is 3.17 moles of carbon, 7.44 moles of nitrogen, and 1.6 moles of hydrogen. Dividing each of these numbers by the lowest number (3.17) gives the ratio of 2 for carbon, 2.35 for nitrogen, and 0.5 for hydrogen.

Answers

A decrease in temperature could account for the weakening of hurricanes when they reach the Atlantic Ocean. hence option A is the correct answer.

How is Hurricane formed?

There must be warm ocean water and wet, humid air in the area for one to form. When humid air flows upward at a low-pressure zone over warm ocean water, water is released from the air, resulting in storm clouds. The air in a hurricane rotates as it rises.

Hurricanes begin with the evaporation of warm seawater, which causes water to be pumped into the lower atmosphere. When converging winds collide and turn upwards, this humid air is pulled aloft.

Hurricanes arise when warm, moist air rises over sea. Cooler air replaces the rising air. Large clouds and thunderstorms continue to form as a result of this process. Because of the Coriolis Effect, these thunderstorms continue to expand and begin to rotate.

Identify at least two physical properties (streak, fracture, etc.) of a mineral while using examples of common minerals that prominently feature those properties. Provide links or screenshots of the discussed minerals to illustrate the highlighted properties. Also, explain what mineral group it belongs to and why.

Answers

The two physical properties of a mineral can be color, streak and even cleavage also.

Color, streak, cleavage, hardness, specific gravity, fracture, luster, and crystal structure are only a few of the many diverse characteristics. I'll speak specifically about color and shine as they relate to diamonds and how they significantly impact the value of the individual stone. Diamonds are a type of carbon polymorph.

Polymorphism, as used in materials science, refers to the fact that a solid material can exist in more than one crystal structure or form. Isomerism in the form of polymorphism. The phenomena can be seen in any crystalline substance. A chemical element's polymorphism is referred to as allotropy. Pharmaceuticals, agrochemicals, pigments, dyestuffs, meals, and explosives all have practical applications for polymorphism. "A reversible transition of a solid crystalline phase at a given temperature and pressure (the inversion point) to another phase of the same chemical composition with a different crystal structure," according to IUPAC, describes a polymorphic transition.

Between what is expected and what actually happens?

Answers

Irony is a mismatch between what is expected and what actually occurs. These literary methods aid in the creation of dramatic effects in writing.

What is Irony?

Irony is a disconnect between what is expected to happen and what actually happens. These types of literary devices help in creating a dramatic effect in literature.

Irony is a literary device which was used extensively in Greek tragedy. It involves expressing the meaning of something by making use of words which technically mean the opposite of the original thing being conveyed.

Irony is used for a dramatic or humorous effect.  There are three types of irony seen in literature as follows:

• Verbal Irony  

• Situational Irony  

• Dramatic Irony  

Verbal irony involves the usage of different words to mean something dissimilar to what they look like they actually mean.  

Situational Irony means that what happens is totally different from what was expected to be happening.

Dramatic Irony occurs in plays, etc. where the audience or the readers are more aware of what is actually going on as compared to the character in the scene.

Enzyme ______ bind to an enzyme to turn it off, thus preventing it from catalyzing a reaction. Multiple choice question

Answers

Enzyme Inhibitors bind to an enzyme to turn it off, thus preventing it from catalyzing a reaction.

An enzyme is a biological molecule that catalyzes chemical reactions in the cell. Enzymes work by lowering the activation energy required for a reaction to occur, making it more likely that the reaction will proceed. However, enzymes can also be inhibited, which means that their activity is reduced or stopped completely. This can happen for a variety of reasons, such as the presence of a specific molecule called an inhibitor.

Some inhibitors bind to the active site of the enzyme, preventing the substrate from binding and thus preventing the reaction from occurring. Other inhibitors bind to other parts of the enzyme, causing a conformational change that prevents the enzyme from working. Still, other inhibitors bind to enzymes and alter their activity by non-covalent interactions.

There are different types of inhibitors like competitive inhibitors bind to the active site of an enzyme and prevent substrate binding. Non-competitive inhibitors bind to a different site on the enzyme, causing a conformational change that makes the enzyme less active. Feedback inhibitors bind to the end product of a metabolic pathway, inhibiting the enzyme that catalyzes the first step of the pathway.

If 1.70g of aniline reacts with 2.10g of bromine, what is the theoretical yield of 4-bromoaniline (in grams)

Answers

If 1.70g of aniline reacts with the 2.10 g of bromine, the theoretical yield of 4-bromoaniline is 2.25 g.

1 mole mole of the aniline react with the 1 mol of Br₂ produces 1 mole of the 4 - bromoaniline.

mass of aniline = 1.70 g

molar mass of aniline = 93 g/mol

moles of aniline = 0.0182 mol

mass of Br₂ = 2.10 g

molar mass of Br₂ = 160 g/mol

moles = 2.10/ 160

         =  0.0131 mol

Br₂ is limiting reagent .

moles of 4-bromoaniline =  0.0131

mass of 4-bromoaniline = moles × molar mass

                                        = 0.0131 × 172

                                         = 2.25 g

Thus, the theoretical yield is 2.25 g.

How many protons neutrons and electrons does carbon-14 have if it has a neutral charge?

Answers

Protons, neutrons and electrons that carbon-14 have if it has a neutral charge is 6 electrons, 8 neutron, and 6 proton.

The total of an element's protons plus neutrons is that element's mass number. One atomic mass unit, or amu, roughly equals the weight of neutrons and protons. While atomic number equal to proton and electron.

The proton can be calculate as follows:

C−14 has atomic no = 6 and mass no = 14.

so

No of electrons = No of protons = atomic no = 6

No of neutron = mass no-atomic no = 14−6=8

Therefore,  Protons, neutrons, and electrons that carbon-14 have if it has a neutral charge is 6 electrons, 8 neutron, and 6 proton.
