Write a balanced chemical equation for each of the following reactions and also classify them.
(a) Lead acetate solution is treated with dilute hydrochloric acid to form lead chloride and acetic acid solution.
Ans. Pb(CH3COO)2 + HCl → PbCl2 + CH3COOH
This is a Double Displacement reaction
(b) A piece of sodium metal is added to absolute ethanol to form sodium ethoxide and hydrogen gas.
Ans. 2Na + 2C2H5ONa + H2
(c) Iron (III) oxide on heating with carbon monoxide gas reacts to form solid iron and liberates carbon dioxide gas.
Ans. 2Fe2O3 + 3CO → 2Fe + 3CO2
This is decomposition reaction.
(d) Hydrogen sulphide gas reacts with oxygen gas to form solid Sulphur and liquid water.
Ans.
2H2O + O2 -> 2S + 2H2O
This is a Redox reaction.
