This equation is known as the ideal gas law, and it can be used to predict the behavior of many gases at relatively low pressure.

from this equation, you can see that as the temperature of a gas increases,
a) the pressure of the gas increases.
b) the number of moles of gas will go down.
eliminate
c) either the pressure of the gas, the volume of the gas, or both, will increase.
d) either the pressure of the gas, the volume of the gas, or both, will decrease.

C

Explanation:

The relationship between

temperature and pressure says that if temperature goes up then the pressure will go up. Same goes for the volume of the ideal gas, it will go up if the temperature increases.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
