Calculate the minimum volume of oxygen gas, at room temperature
and pressure (rit. required to completely burn 56g of methane gas.
give your answer to two significant figures.
(1 mole of any gas occupies 24 dm at rt. p., a, c = 12, h = 1)

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

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
