Stoichiometry of Magnesium and Hydrochloric Acid Reaction
Easy General Chemistry Stoichiometry And Chemical Reactions
A chemical reaction occurs when magnesium (Mg) reacts with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2). The balanced chemical equation for this reaction is:
Mg + 2 HCl → MgCl2 + H2
If 2.0 moles of magnesium are reacted with excess hydrochloric acid, how many moles of hydrogen gas will be produced?
