Question

calcium carbonate decomposes on heating, to form calcium oxide. when 10g of calcium carbonate is decomposed completely, then 5.6g of calcium oxide is formed. calculate the mass of carbon di oxide formed.​

Answer 1

Answer:

Using conservation of mass

10 g of calcium carbonate produces 5.6 g of calcium oxide. How much carbon dioxide is made? If you start with 10 g of reactant, you must end up with 10 g of product. 5.6 g of the product is calcium oxide, so 10 – 5.6 = 4.4 g of carbon dioxide.
