Question

10g of caco3 on heating gave 4.4g of co2 and 5.6g of cao. The observation is in agreement with the law of ____________________

Answer 1

law of conservation of mass.

Answer 2

Answer:

The observation is in the agreement with the law of conservation of mass.

Explanation:

Given:

10g of $\mathrm{CaCo}_{3}$ on heating will give 4.4g of co2 and 5.6g of cao

Here $\mathrm{CaCo}_{3}$ is considered to be as the reactant and $\mathrm{Co}_{2}$ and CaO are said to be as the products.

To prove the law is law of conservation of mass

Consider,

Mass of reactants in an chemical equation=10g

Mass of products formed due to the chemical reaction=4.4+5.6=10g

Hence, above explanation shows conservation of mass.

From the above expression we can conclude that,

Mass of reactants = mass of products which shows the conservation of mass.

Hence it is proved that the above expression is said to be as the law of conservation of mass.
