Problem: When 56.6 g of calcium and 30.5 g of nitrogen gas undergo a reaction that has a 93.0% yield, what mass (g) of calcium nitride forms?

FREE Expert Solution

The reaction of calcium metal and nitrogen gas produces calcium nitride. The chemical equation is:

This is not yet balanced; just add a coefficient of 3 to Ca on the reactant side to balance the equation.

We first need to determine which between Ca and N2 is the limiting reactant. The reactant that forms the lower amount of product is the limiting reactant and will dictate the theoretical yield of the reaction. The molar mass of Ca3N2 is 3(40.08 g/mol Ca) + 2(14.01 g/mol N) = 148.26 g/mol.
