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, 14.5 g of MgO are collected.

a) Determine the limiting reactant for the reaction.

b)Determine the theoretical yield for the reaction.

c)Determine the percent yield for the reaction.
