The ability of an element to react is the elements

Sladkaya [172]

Answer:

Option D. There will be a shift toward the reactants.

Explanation:

The reaction is:

$PCl_5(g)+heat\rightleftharpoons PCl_3(g)+Cl_2(g)$

The application of LeChatelier's principle leads to consider the heat as a reactant or a product depending on if it is on the left side or the right side.

In this reaction, the heat is on the left side, thus it must be considered a reactant.

Decreasing the temperature is equivalent to remove or consume heat. Thus, the reaction must shif to the left to compensate that reduction of heat. That is the reverse reaction shall be favored.

In conclusion, there will be a shift toward the reactants.

An acid solution contains more... ions than... ions.

spayn [35]

Answer: An acid contains more hydrogen ions than hydroxide ions.

Explanation:

An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton $(H^+)$ donors when they have high concentration of hydrogen ions.

A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton $(H^+)$ acceptors when they have low concentration of hydrogen ions.

Hence, an acid is contains more hydrogen ions than hydroxide ions.

What information does the rate constant give from the rate law? A. It tells how much the rate of the reaction is affected by vol

Levart [38]

From the rate law, the information that is given by the rate constant is: C. It tells how much the reaction rate is affected by activation energy.

Rate law is also referred to as rate equation and it can be defined as a chemical equation that is typically used to relate the initial (forward) chemical reaction rate with respect to the concentrations or pressures of the chemical reactants and constant parameters.

Mathematically, the rate law is given by this formula:

$R = k[A]^x[B]^y$

Where:

k is the rate constant.

A is the concentration of reactant A.

B is the concentration of reactant B.

In Chemistry, the rate constant is typically used to tell the reaction rate or rate of a chemical reaction that is affected by activation energy.

A rigid container has 44.5 grams of oxygen gas at room temperature and a pressure of 2.3 atm. How many grams of oxygen should th

Travka [436]

Answer:

The mass of oxygen the container must have is 150.85 g.

Explanation:

Given;

mass of the oxygen, m₁ = 44.5 g

initial pressure of the gas, P₁ = 2.3 atm

final pressure of the gas, P₂ = 7.8 atm

Atomic mass of oxygen gas, = O₂ = 16 x 2 = 32 g

initial number of moles of oxygen in the container, n₁ = 44.5/32 = 1.39

let the final number of moles of oxygen = n₂

Apply ideal gas equation;

PV = nRT

$\frac{PV}{Rn} = T\\\\since \ temperature\ T \ is \ constant;\\\\\frac{P_1V}{Rn_1} = \frac{P_2V}{Rn_2}\\\\\frac{P_1}{n_1} = \frac{P_2}{n_2} \\\\n_2 = \frac{n_1P_2}{P_1} \\\\n_2 = \frac{1.39 \times 7.8}{2.3} \\\\n_2 = 4.714 \ moles$

The mass of the oxygen in grams is calculated as;

m₂ = 4.714 x 32g

m₂ = 150.85 g

Therefore, the mass of oxygen the container must have is 150.85 g.
