Question

10g of calcium carbonate decomposes completly on heating to give 5.6g of calcium oxide. Calculate the mass of carbon dioxide formed. Which law of chemical combination will you use in solving the problem ?​

Answer 1

Answer:

Hai friends,

Here is ur ans;

(*)The mass of carbon dioxide = The total mass of calcium carbonate - Mass of calcium oxide

=10.0g-5.6g

=4.4g

(*)Law of conservation of mass:

The law of conservation of mass states that "the mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass , the mass of products in a chemical reaction must equal to the mass of the reactants.
