According to the reaction shown, how many moles of oxygen gas are necessary to produce 24.0 g of Li2O?
4Li(s) + O2(s) — 2L120(s)
O A. 0.8 mol
O B. 1.6 mol
O C. 1.0 mol
O D. 0.4 mol

2b2t

explanation:

2b2t

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

5.6⋅10−^19  j
