Question

20g of caco3 on heating gave 8.8g of CO2 and 11.2g of CaO.this is in accordance with​

Answer 1

Explanation:

law of conservation of mass

Answer 2

Given - Mass of reactants and products

Find - Law

Solution - The given data is following the law of conservation of mass.

• The mentioned reaction is the decomposition reaction. Calcium carbonate dissociates to form calcium oxide and carbon dioxide gas.
• Thus, the mass on the reactant's side is 20 grams.
• Mass of products = 8.8 + 11.2
• Mass of products = 20 gram
• Thus, mass is conserved on both the reactant and product sides. So, it is following the law of conservation of mass.
• As per the law of conservation of mass, the mass remains constant over time.
