Question

It has been found by experiment that if hundred gram of calcium carbonate decomposed completely then 56 gram of calcium carbonate and 44 gram carbon dioxide

Answer 1

Answer:

The above equation follows law of conservation of mass.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The chemical equation for the decomposition of calcium carbonate follows:

CaCO_3\rightarrow CaO+CO_2

We are given:

Mass of calcium carbonate = 100 grams

Mass of calcium oxide = 56 grams

Mass of carbon dioxide = 44 grams

Total mass on reactant side = 100

Total mass on product side = 56 + 44 = 100 g

Hence, the above equation follows law of conservation of mass.
