3) In the combustion reaction of methane gas : CH4 (g) + O2 (g) CO2 (g) + 2 H20 (g) 4.0 X 10 exp 23 molecules of CH4 was used. Determine (a) the moles of CO2 produced. ​

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
