Question

Write the balanced chemical equations for the following reactions:

Hint:

Balanced chemical equations are essential for understanding the stoichiometry of reactions.

Answer 1

(i) Lead nitrate is heated:
\[ 2 \, \text{Pb(NO}_3\text{)}_2 \xrightarrow{\text{heat}} 2 \, \text{PbO} + 4 \, \text{NO}_2 + O_2 \]
(ii) Ethanoic acid reacts with Sodium carbonate:
\[ \text{CH}_3\text{COOH} + \text{Na}_2\text{CO}_3 \rightarrow 2 \, \text{CH}_3\text{COONa} + \text{CO}_2 + H_2O \]
(iii) Reaction of Zinc with Silver nitrate:
\[ \text{Zn} + 2 \, \text{AgNO}_3 \rightarrow \text{Zn(NO}_3\text{)}_2 + 2 \, \text{Ag} \]
(iv) Reaction of Sodium sulphate solution with Barium chloride solution:
\[ \text{Na}_2\text{SO}_4 + \text{BaCl}_2 \rightarrow \text{BaSO}_4 + 2 \, \text{NaCl} \]
