Question

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

Answer 1

copper carbonate & sodium sulphate ( bad conductor of heat)

Answer 2

Answer:

The product formed are copper carbonate and sodium sulfate.

Explanation:

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

This also means 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)
