Answer 2

Law of conservative of Mass experiment:

A. The above experiment proves that : in a chemical reaction mass can neither be created nor destroyed.

The reactants —> atoms of one or more substances simply get rearranged to form product.

(Law of conservation of mass)

B. Equation :

BaCl2(aq) +Na2So4 (aq) ->BaSO4(s)+ 2NaCl (aq)

Note:Write the digits at the end of chemical compounds as subscript.

C. In a nuclear reaction, some the mass gets converted into energy creating an imbalance between the mass of reactants and the products. Therefore, the total mass is not conserved. This is the limitation of the conservation of mass.
