Answer 2

Explanation:-

According to the given reaction.

The law of chemical combination illustrated is Law of Conservation of mass.

$CaCO_3 \rightarrow CaO + CO_2$

According to The law of Conservation of mass :-

This law is given Anotaine van Lavousier in 1789.

The mass during any chemical reaction is conserved that means sum of mass of reactants and products during chemical reaction is same.

• Mass of Reactants = Mass of products

Mass of Reactants → 100 g

Mass of products → 56 + 44

= 100 g

Hence,

It verifies law of conservation of mass.
