Question

2 Ca + O2 2 CaO

If this reaction occurs with 5 moles of Ca and 5 moles of O2, how much CaO will be produced?

Answer 1

Answer:

5mol at most

Explanation:

as we hv 5mol Ca available, the 5 mol Ca can react with 5/2 = 2.5mol O2, as we have more mol of O2 than that Ca can react with, Ca is the limiting reactant. Therefore at most 5/2x2 = 5 mol of CaO can be made
