Magnesium oxide can be made by heating magnesium metal in the presence of oxygen. The balanced equation for the reaction is: 
2Mg(s)+O2(g)→2MgO(s) When 10.1 g of Mg are allowed to react with 10.5 g of O2, 10.2 g of MgO are collected. 

A. Determine the limiting reactant for the reaction. 
B. Determine the theoretical yield for the reaction. 
C. Determine percent yield for the reaction.
