Stoichiometry of Magnesium Reaction with HCl
Medium General Chemistry Stoichiometry And Chemical Reactions
A laboratory experiment involves the reaction of magnesium (Mg) with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2). The balanced chemical equation for this reaction is:
Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g)
If 0.075 moles of magnesium are reacted with an excess of hydrochloric acid, how many moles of hydrogen gas (H2) will be produced?
