Question

When we react copper sulphate and sodium carbonate to prove the law of conservation of mass, write the product formed.

SUPER URGENT!!! PLEASE!!!

Answer 1

CuSo4and Na2CO3.......................

Answer 2

Answer:

The product formed are copper carbonate and sodium sulfate.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

In a balanced chemical reaction that total mass on the reactant side must be equal to the total mass on the product side.

$CuSO_4+Na_2CO_3\rightarrow CuCO_3+Na_2SO_4$

Molar mass of copper sulfate = 143.5 g/mol

Molar mass of sodium carbonate = 106 g/mol

Molar mass of copper carbonate = 123.5 g/mol

Molar mass of sodium sulfate = 126  g/mol

Total mass of reactant = Total mass of product

143.5 g/mol + 106 g/mol = 123.5 g/mol + 126  g/mol

249.5 g/mol = 249.5 g/mol  (Law of conservation of mass proved)
