Silicon nitride is a very hard, high-temperature-resistant ceramic used as a component of turbine blades in jet engines. Upon reaction of 38.6 g solid silicon with excess nitrogen, 44.8 g of silicon nitride was obtained according to the balanced equation: 3 Si(s)+2 N2(g)⟶Si3N4(s) What is the percent yield of silicon nitride?
