Question

B. If law of conservation of mass holds good, predict Low much the
residue would weigh if 4.2g of NaHCO3, 10g CH3COOH is added
and 2.2g of CO2 is released?​

Answer 1

Explanation:

Answer: The law of conservation of mass is proved below.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only transform from one form to another. Mass remains conserved in a chemical reaction.

In a chemical reaction, total mass on the reactant side is always equal to the total mass on the product side.

For the given chemical reaction:

Total mass on the reactant side =

Total mass on the product side =

As, the total mass on the reactant side is equal to the total mass on the product side. Thus, law of conservation of mass is satisfied.
