Hydrazine, N2H4, is an oily liquid used as a rocket fuel It can be prepared in water by oxidizing ammonia with hypochlorite ions 2 NH3g ClOaq > N2H4aq Claq H2Ol When 350 g of ammonia reacted with an excess of hypochlorite ion, 252 g of hydrazine was produced What is the percentage yield of hydrazine?The percentage yield is the ratio of actual yield to theoretical yield expressed as a percentage (37 g/100 g) × 100% = 37%Y p is the percentage yield (%) Y t is the theoretical yield Percent Yield Definition And Formula What is actual yield in chemistry
