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...

Liquid silicon tetrachloride reacts violently with liquid water to product solid silicon dioxide and aqueous hydrochloric acid. Write a balanced equation for this reaction. If 76.5 g of water is mixed with 275 g of silicon tetrachloride and the reaction goes to completion, how many grams of silicon dioxide can be produced? [97.3 g SiO2] How many grams of the nonlimiting (excess) reagent remain unreacted when the reaction is over? [18.2 g H2O] If the percent yield for the reaction...

A cast aluminium-silicon alloy containing 12 % silicon which cannot be age hardened would normally solidify with a hyper-eutectic structure. This alloy can be used for both sandcasting and metal die-casting. Describe THREE methods in which the cast metal can be strengthened by controlling the microstructure during solidification.
