Question

10 g CaCO3 decomposes to give 5.6 g of Cao. What will be the mass of CO2 obtained ?​

Answer 1

Explanation:

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.

Hope its help.
