1. Balance the chemical equation between Mg and HCl.

2. What type of reaction occurs between Mg and HCl?

3. Show how you would calculate the % yield of hydrogen if 40.0 grams of magnesium react with an excess of nitric acid producing 1.70 grams of hydrogen gas. Mg + 2 HNO3 --- Mg(NO3)2 + H2.

The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas.
