ANSWER:Solution 70 QPHere we have to determine the limiting reactant, and calculate the moles of product in parentheses that would form.For each of the following reactions, 3.00 moles of each reactant is present initially. Step-1a. 4Li(s) + O2(g) 2Li2O(s) (Li2O)In this reaction 2 moles of Li2O has formed from 4 mol of Li and 2 moles of Li2O has formed from 1 moles of O2.Mole of Li2O produced from Li3.00 mole of Li = 1.5 mol of Li2OMoles of Li2O produced from O23.00 mole of O2 = 6 mol Li2OIt is known that the reactant which run out first and producing the smalle
