Question

Complete the following reaction to predict the products formed:
1. An aqueous solution of lead nitrate is added to sodium sulphate
2. Zinc sulphide pellets are added to an aqueous solution of hydrochloric acid​

Answer 1

Answer:

On mixing an aqueous solution of lead nitrate with sodium sulphate, a white precipitate of lead sulphate is formed.

Pb(NO3)2 + Na2SO4 → 2 NaNO3 + PbSO4

ZnS+2HCL→ZnCl2+H2S

Explanation:

Answer 2

Explanation:

1.On mixing an aqueous solution of lead nitrate with sodium sulphate, a white precipitate of lead sulphate is formed.

2.Here a double displacement reaction will take place where when the reactants ZnS and HCL will react to form ZnCl2 and H2S gas will be evolved. So the products are Zinc Chloride and Hydrogen Sulphide gas, the balanced reaction

ZnS+2HCL→ZnCl2+H2S
