Question

if the the law of conservation of mass holds good how much would the Residue way when 96 gram of caco3 is heated and 12.2 gram of Co2 is released
Please help ​

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:

CaCO3→CaO+CO2

 100 gm      56 gm    44 gm

When 10g of CaCO3 is decomposed, 5.6g of residue is left and 4.4g of CO2 is escapes follows "Law of mass conservation".

Hence, option A is correct.
