Answer:
The above equation follows law of conservation of mass.
Step-by-step 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_2CaCO3→CaO+CO2
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.
