Question

Write out and balance the following chemical reactions:

1. Copper sulphate + sodium carbonate
2. Barium Chloride + sodium sulphate
3. Lead nitrate + sodium chloride

Answer 1

CuSO4 + Na2CO3 ➡️CuCO3 + Na2SO4.

BaCl2 + Na2SO4 ➡️ BaSO4 + 2NaCl.

Pb(NO3)2 + 2NaCl ➡️ PbCl2 + 2NaNO3.

Answer 2

1.CuSO4+Na2CO3=CuCO3Na2SO4.

2.BaCl2 + Na2SO4 = BaSO4+2NaCl.

3.Pb(NO3)2 +2NaCl=PbCl2+2NaNO3.
