\( 16.8 \mathrm{g} \) of metal carbonate on thermal decomposition gave 8 g of metallic oxide and \( 8.8 \mathrm{g} \) of carbon dioxide. They follow:

1. Law of constant proportion
2. Law of multiple proportion
3. Law of conservation of mass
4. None of the above

Correct answer: Law of conservation of mass

Solution

The reactant mass is 16.8 g, and the products are 8.0 g oxide plus 8.8 g carbon dioxide, which also totals 16.8 g. Since mass is neither created nor destroyed, this illustrates the law of conservation of mass.
