Question

if 100 grams of calcium carbonate decompose completely then 56 grams of calcium oxide and 44 grams of carbon dioxide are obtained which law of chemical combination is illustrated by the statement

Answer 1

It is the Law of conservation of mass given by scientist Lavioser because if CaO=56gms and CO2=44gms so total mass = 100 gms and according to the ques the mass of CaCO3 is 100gms

Answer 2

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.
