The equilibrium constant for the following equation:
Mkey [24]

From the calculation, the partial pressure of Cl2 is 1.98 atm. Option B

<h3>What is the equilibrium constant?</h3>

The term equilibrium constant refers to the value that shows us the extent to which reactants are converted into products. We know that the equilibrium constant can only be obtained by the use of the equilibrium partial pressures of each of the species.

Thus we have;

K = p PCl3 . pCl2/pPCl5

p PCl3 = partial pressure of PCl3

pCl2 = partial pressure of Cl2

pPCl5 = partial pressure of PCl5

K = equilibrium constant

Substituting values;

1.05 =  0.463 *  pCl2/0.875

 pCl2 = 1.05  * 0.875/0.463

pCl2 = 1.98 atm

Every pure substance has exact and specific density. What are two purposes that a chemist would use a calculated density for.
adell [148]

Answer:

1. Density can be used to identify a substance

2. Density can be used to ascertain whether a substance will float in water.

Explanation:

The calculation of the density of a substance can be used to identify the substance. If the density of a substance is calculated accurately, and compared with a table of standard densities, then we can identify that substance.

Also, density determines whether an object will float or sink in water. If an object is less dense than water then it will float in water. If it is denser than water, then it will sink in water.
