1. Write the balanced chemical equations for the following reactions.
Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride water and liberates carbon dioxide.
The balanced chemical equation of the above statement is
+ \(HCl\) →
2. Ferrous sulphate decomposes with the evolution of a gas having a characteristic odour of burning sulphur. Write the chemical reaction involved and identify the type of reaction.
Balanced equation for the given statement is
\(\xrightarrow[]{Heat}\) \(Fe_2O_3\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
On heating, ferrous sulphate decomposes into ferric oxide, sulphur dioxide, and sulphur trioxide. Therefore this is a reaction (decomposition on heat).
