Answer:

A) Mass

Explanation:

The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.

What is Keg for the reaction N2 + 3H2 = 2NH2 if the equilibrium
AlladinOne [14]

<u>Answer:</u> The equilibrium constant for the given reaction is 1.33

<u>Explanation:</u>

We are given:

Equilibrium concentration of ammonia = 2 M

Equilibrium concentration of nitrogen gas = 3 M

Equilibrium concentration of hydrogen gas = 1 M

For the given chemical equation:

N_2+3H_2\rightleftharpoons 2NH_3

The expression of K_{eq} for above equation follows:

K_{eq}=\frac{[NH_3]^2}{[N_2][H_3]^3}

Putting values in above equation, we get:

K_{eq}=\frac{(2)^2}{3\times (1)^3}\\\\K_{eq}=1.33

Hence, the equilibrium constant for the given reaction is 1.33

mrs_skeptik [129]

Answer:

VP as function of time => VP(Ar) > VP(Ne) > VP(He).

Explanation:

Effusion rate of the lighter particles will be higher than the heavier particles. That is, the lighter particles will leave the container faster than the heavier particles. Over time, the vapor pressure of the greater number of heavier particles will be higher than the vapor pressure of the lighter particles.

=> VP as function of time => VP(Ar) > VP(Ne) > VP(He).

Review Graham's Law => Effusion Rate ∝ 1/√formula mass.
