Problem

Sodium and nitrogen combine to form sodium nitride;

6Na(s)+N2(g) → 2Na3N(s)

a) if 80.0 g of sodium is mixed with 20.0 g of nitrogen gas, what mass sodium nitride forms?

b) If the reaction in part "a)" has a percent yield 75.0%, how much sodium nitride is actually produced?

Solution

Recall: Limiting reactant - the reactant that is consumed completely during a chemical reaction. It limits the amount of product formed, as it is consumed first.
Percent yield - percent ration of the actual yield by the theoretical yield. It tells us how efficient the reaction was.
