Question

100g caco3 decomposes to give 56g of cao and 44g of co2 which law chemical combination is illustrated here.state the law

Answer 1

Answer:

Law of conservation of mass.

Explanation:

For a reaction to be conserved for mass, the amount of summation of the  reactant will be equal to the amount of the product while the reaction.

For the above reaction we have that the mass of the reactant to be on solving as 100g. While the mass of the product on summation will also give as 56+44 which is 100g. So, it is clear that the summation of the reactant mass and the product mass is same so the law is proven.
