Question

if 10 g of barium chloride is mixed with 15g of sodium sulphate what will be the total mass of the products formed?

Answer 1

If the 10 gram of BaCl2 is mixed with 15 gram of sodium sulphate then the total mass of the products is equal total mass of rectants

Answer 2

Answer: The total mass of the products formed is equal to 25 g.

Explanation: According to law of conservation of mass, the mass of the reactants must be equal to the mass of the products as mass can neither be created nor be destroyed.

$BaCl_2+Na_2SO4\rightarrow BaSO_4+2NaCl$

As the mass of reactants = Mass of $BaCl_2$ + mass of $Na_2SO4$ = 10g+15 g= 25g

Thus mass of the products $BaSO_4$ and $NaCl$ = 25 g
