Metallic magnesium reacts with steam to produce magnesium hydroxide and hydrogen gas. If 17.1 g of Mg are heated with 9 g of H2O, what is the limiting reactant? I know limiting reactant is H2O. How much of the excess reactant is left? Answer in units of mol How much Mg(OH)2 is formed?How much H2 is formed? Answer in units of g?
