Potassium chlorate (used in fireworks, flares, and safety matches) forms oxygen and potassium chloride when heated.KClO3(s) → KCl(s) + O2(g) [unbalanced]What mass of oxygen gas is formed if 26.4 g of potassium chlorate decomposes completely?

The first step in the Ostwald process for producing nitric acid is as follows:4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g).If the reaction of 15.0 g of ammonia with 15.0 g of oxygen gas yields 8.70 g of nitric oxide, what is the percent yield of this reaction?
