1. What mass of KClO3 will produce 48.00 g of O2 if the decomposition of KClO3 is complete? (The answer is 122.5) Can you explain how to get to this answer?
2. When 1.187 g of a metallic oxide is reduced with excesshydrogen, 1.054 g of the metal is produced. What is the metallicoxide? (the answer is Cu2O) can u explain how to obtain this answer?
3. Ammonia reacts with OCl- to produce N2H4. How many moles of N2H4 are produced from 5.85 mol of ammonia if the reaction has a 78.2%yield? (the answer is 2.29 mol, can you explain how to get it)
2NH3 + OCl- ---- N2H4 +Cl- + H2O
