- (A) The balanced equation shows that 1 mole of zinc requires 2 moles of
hydrochloric acid to completely react. The masses provided show only
1.0 mole of hydrochloric acid (36.5 g) is present to react with the 1.0 mole of
zinc (65 g), indicating that the hydrogen chloride is the limiting reactant.
Because the balanced equation also shows that 1 mole of hydrogen is
produced for every 2 moles of hydrogen chloride reacted, the number of moles
of hydrogen gas that can be produced is 0.50.
