Silicon nitride (Si3N4) is made by combining elemental silicon with nitrogen gas at a high temperature. a.) How many grams of silicon are needed to react with an excess of nitrogen to prepare 150. grams of silicon nitride? b.) How many grams of nitrogen would need to react? c.) If you determine that 0.950 moles of silicon nitride were formed in this reaction, what would be the percent yield? Give two possible explanations for why the percent yield would be that value.
