The reaction is 4A = 2B + 3C

Q = Products / Reactions

If there are numbers in front of the molecules, they turn into exponents

So the answer is C) Q = [B]^2 [C]^ 3/ [A]^4

Answer:

C) Q = [B]02 [C] 03/[A] 04

Explanation:

Hello,

In this case, based on the Law of Mass action, which states that the product of the concentration of the products divided the product of the concentration of the reactants both to the stoichiometric coefficient power equals the reaction quotient, we obtain for the given reaction:

$4A2B+3C\\\\Q=\frac{[B]^2[C]^3}{[A]^4}$

Therefore, the answer is C).

Best regards.

Consider the equilibrium system below.

Neporo4naja [7]

Answer:

C. The rate of sublimation of the NH₄CI crystals is equal to the rate of solidification of the NH₄CI vapors.

Explanation:

The question is garbled and the reactants and products do not match.

This is the correct question, assuming the products are correctly described:

"Consider the equilibrium system below.

$NH_4Cl(s)\rightleftharpoons NH_4Cl(g)$

If the system is at dynamic equilibrium, which statement is true?

A. Sublimation of the NH₄CI crystals stops.

B. Solidification of the NH₄CI vapors stops.

C. The rate of sublimation of the NH₄CI crystals is equal to the rate of solidification of the NH₄CI vapors.

D. The rate of sublimation of the NH₄CI crystals is higher than the rate of solidification of the NH₄CI vapors"

<h2>Solution</h2>

The left side of the equation shows solid NH₄CI. The right side shows gas NH₄CI.

Thus, the equation represents the equilibrium between the formation of crystals (solid) and vapors (gas) of the compound NH₄CI.

The change from solid state to gas state is represented by the forward reaction (fom left to the right). It is named sublimation.

The change from vapors to crystals (named deposition) is represented by the reverse reaction (from right to left).

Dynamic equilibrium means that the molecules continually form vapors and cristals at the same speed. Thus, the final result is that each the total number of molecules of vapors and the total number of molecules of crystals do not change.

In conclusion, "The rate of sublimation of the NH₄CI crystals is equal to the rate of solidification of the NH₄CI vapors" (option C).

A dilute solution of bromine in carbon tetrachloride behaves as an ideal-dilute solution. The vapour pressure of pure CCl4 is 33

ANEK [815]

Explanation:

The given data is as follows.

Vapour pressure of pure $CCl_{4}$ = 33.85 Torr

Temperature = 298 K

Mole fraction of $Br_{2}$ = 122.36 torr

Therefore, calculate the vapor pressure of $Br_{2}$ as follows.

Vapour pressure of $Br_{2}$ = mole fraction of $Br_{2}$ x K of $Br_{2}$

= 0.050 x 122.36 Torr

= 6.118 Torr

So, vapor pressure of $Br_{2}$ is 6.118 Torr .

Now, calculate the vapor pressure of carbon tetrachloride as follows.

Vapour pressure of $CCl_{4}$ = mole fraction of $CCl_{4}$ x Pressure of $CCl_{4}$

= (1 - 0.050) × 33.85 Torr

= 32.1575 Torr

So, vapor pressure of $CCl_{4}$ is 32.1575 Torr .

Hence, the total pressure will be as follows.

= 6.118 Torr + 32.1575 Torr

= 38.2755 Torr

Therefore, composition of $CCl_{4}$ = $\frac{32.1575 Torr}{38.2755 Torr}$

= 0.8405

Composition of $CCl_{4}$ is 0.8405 .

And, composition of $Br_{2}$ = $\frac{6.118 Torr}{38.2755 Torr}$

= 0.1598

Composition of $Br_{2}$ is 0.1598 .

An ionic compound is composed of the following elements: Nitrogen – 31.57% Hydrogen – 9.10% Phosphorus – 23.27% Oxygen – 36.06%

malfutka [58]

Answer:

N3H12PO3

Explanation:

Step 1:

Data obtained from the question.

Nitrogen (N) = 31.57%

Hydrogen (H) = 9.10%

Phosphorus (P) = 23.27%

Oxygen (O) = 36.06%

Step 2:

Divide by their molar masses.

This is illustrated below:

N = 31.57/14 = 2.255

H = 9.10/ 1 = 9.1

P = 23.27/31 = 0.751

O = 36.06/16 = 2.254

Step 3:

Divide by the smallest number. This is illustrated below:

N = 2.255/0.751 = 3

H = 9.1 /0.751 = 12

P = 0.751 /0.751 = 1

O = 2.254/0.751 = 3

The empirical formula is N3H12PO3
