Question

10g CaCO3 on heating gives 5.6g CaO and ____g CO2?​

Answer 1

Law of conservation of mass states that matter can be changed from one form to another but the total amount of mass remains constant. The total mass of the products formed is the same as the total mass of the reactants

Answer 2

Answer:

The correct answer will be -

10 g CaCO₃ on heating gives 5.6 g CaO and 4.4 g CO2.

Explanation:

According to the law of conservation of the mass -

• The mass of the product should be equal to the mass of the reactants.
• So, if take the mass of CO₂ to be x the mass of the product will be 5.6 + x and the mass of reactants is 10 g.

$10 = 5.6 +x \\\\x = 10-5.6\\\\x = 4.4 g$

So the mass of the CO₂ will be 4.4 g.
