The decomposition of potassium chlorate produces potassium chloride and oxygen gas. The
decomposition of a sample of potassium chlorate produces 4.84g of oxygen and 7.51g of
potassium chloride. What mass of oxygen will be produced from the decomposition of a 3.45g
sample of potassium chlorate?
Also, are decomposition problems doner differntly? or is there a tip on how to approach them?
