Lime, CaO, is produced by heating calcium carbonate, CaCO 3 : carbon dioxide is the other product. (a) Outline the steps necessary to answer the following question: What volume of carbon dioxide a 875 K and 0966 atm is produced by the decomposition of 1 ton ( 1.000 × 10 3 kg ) of calcium carbonate? (b) Answer the question.
