The characteristic properties of acids and bases — practice question

When magnesium is added to dilute hydrochloric acid, a salt and hydrogen gas are formed. What is the equation for this reaction?

  • A$\text{Mg} + \text{HCl} \rightarrow \text{MgCl} + \text{H}$
  • B$\text{Mg} + \text{H}_2\text{Cl}_2 \rightarrow \text{MgCl}_2 + \text{H}_2$
  • C$\text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2$
  • D$\text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + 2\text{H}$
