Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.01 mol of magnesium and 3.01 mol of hydrochloric acid are reacted, how many moles of magnesium chloride are produced?

Question

Quizplus · Accepted Answer

The balanced chemical equation is Mg + 2HCl → MgCl2 + H2. Since 2 moles of HCl are needed for every mole of Mg, HCl is the limiting reactant. With 3.01 mol of HCl, only 1.505 mol of MgCl2 can be produced.
