Question

Q.3 Write the balanced chemical equation for the following reactions.
1. Calcium hydroxide + Carbon dioxide -> Calcium carbonate + Water
2. Zinc + Silver nitrate - > Zinc nitrate + Silver
Aluminium + Copper chloride --> Aluminium chloride + Copper
4. Barium chloride + Potassium sulphate-> Barium sulphate + Potassium chloride​

Answer 1

The balanced chemical equations are below:

1) Ca(OH)2 + CO2 ---> CaCO3 + H2O

2) Zn + 2AgNO3 ---> Zn(NO3)2 + 2Ag

3) 2Al + 3CuCl2 ---> 2AlCl3 + 3Cu

4) BaCl2 + K2SO4 ---> BaSO4 + 2KCl

Hope it helps!!
