When carbohydrate is metabolized without oxygen, it is called what?

The following will be true regarding the relative partial pressures of the gases remaining in the vessel after some of the gas mixtures have effused. Pressure H₂ < Pressure  N₂ < Pressure Ar

Let us first write the formula for Graham's law of diffusion/effusion to answer this question.

r ∝ 1/√M

Where;

r denotes the diffusion/effusion rate.

M denotes molar mass.

In effusion, a barrier with very small holes usually prevents the gas from rapidly expanding into a new volume. As a result, the heavier the gas, the slower the effusion rate; the lighter the gas, the faster the effusion rate.

Now, the heavier gas has a higher pressure than the lighter ones.

The molar masses of the following gases are as follows:

Molar mass of H₂ = 2.016 g/mol

Molar mass of Ar = 39.95 g/mol

Molar mass of N₂ = 28.0134 g/mol

The rate of effusion is inversely proportional to the molar mass, according to the effusion equation.

As a result, the higher the molar mass, the lower the effusion rate and, as a result, the higher the pressure because it is a heavy gas.

As a result, Ar has the greatest molar mass and will experience the greatest pressure.N₂  comes next, followed by H₂.

If a container is filled with more than one gas, each gas exerts pressure on the container. The partial pressures of any gas within the container are referred to. Partial pressure is the pressure exerted by one of the gases in the mixture if it occupies the same volume on its own.

The kinetic energy of a 23.2-g object moving at a speed of 98.7 m/s is  113.30 J. Option D

The kinetic energy of an object can be calculated using the formula: KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity or speed of the object.

Given:

Mass (m) = 23.2 g = 0.0232 kg

Speed (v) = 98.7 m/s

Substituting these values into the formula, we can calculate the kinetic energy:

KE = (1/2)(0.0232 kg)(98.7 m/s)^2

KE = (1/2)(0.0232 kg)(9756.09 m^2/s^2)

KE ≈ 113.30 J

Therefore, the kinetic energy of a 23.2-g object moving at a speed of 98.7 m/s is approximately 113.30 J.

It's worth noting that the question is repeated twice, but the answer remains the same. The kinetic energy of the object is determined by its mass and speed, and both calculations yield the same result. Option D

Explanation:

Let is consider the molecular equation;

2NaOH(aq) + Cr(NO3)2(aq) -----> 2NaNO3(aq) + Cr(OH)2(s)

This is a double displacement or double replacement reaction. The reacting species exchange their partners. We can see here that both the sodium ion and chromium II ion both exchanged partners and picked up each others partners in the product.

Sodium ions and nitrate ions now remain in the solution while chromium II hydroxide which is insoluble is precipitated out of the solution as a solid hence the answer.

The volume of hydrogen gas produced in the reaction of 73 grams of zinc and 73 grams of hydrochloric acid (under normal conditions) is approximately 22.4 liters.

To calculate the volume of hydrogen gas produced in the reaction of zinc and hydrochloric acid, we need to use the principles of stoichiometry and the ideal gas law.

First, let's write the balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl):

Zn + 2HCl →\(ZnCl_2\)+ H2

From the equation, we can see that one mole of zinc reacts with two moles of hydrochloric acid to produce one mole of hydrogen gas. To determine the number of moles of zinc and hydrochloric acid, we need to convert the given masses into moles.

The molar mass of zinc (Zn) is approximately 65.38 g/mol, so 73 grams of zinc is equal to:

73 g Zn * (1 mol Zn / 65.38 g Zn) ≈ 1.116 mol Zn

Similarly, the molar mass of hydrochloric acid (HCl) is approximately 36.46 g/mol, so 73 grams of HCl is equal to:

73 g HCl * (1 mol HCl / 36.46 g HCl) ≈ 2.002 mol HCl

According to the balanced equation, the reaction produces one mole of hydrogen gas for every two moles of hydrochloric acid. Therefore, since we have 2.002 moles of HCl, we expect to produce half that amount, or approximately 1.001 moles of hydrogen gas.

To calculate the volume of hydrogen gas, we can use the ideal gas law, which states:

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. In this case, we assume the reaction is conducted under normal conditions, which means a pressure of 1 atmosphere and a temperature of 273.15 Kelvin.

Rearranging the equation to solve for V, we have:

V = nRT / P

Substituting the values, we get:

V = (1.001 mol) * (0.0821 L·atm/(mol·K)) * (273.15 K) / (1 atm) ≈ 22.4 L

Therefore, the volume of hydrogen gas produced in the reaction is approximately 22.4 liters.

Answer:

Arrhenius Acid = HBr

Arrhenius Base = LiOH

Explanation:

Arrhenius acids are substances which increase the H⁺ concentration of an solution it has been dissolved in.

Arrhenius bases are substances which increase the OH⁻ concentration of a solution it has been dissolved in.

When dissolved in a solution, HBr dissociates into H⁺ and Br⁻ ions. As such, HBr increases the H⁺ concentration of the solution and is a Arrhenius acid.

When dissolved in a solution, LiOH dissociates into Li⁺ and OH⁻ ions. As such, LiOH increases the OH⁻ concentration of the solution and is an Arrhenius base.
