1. Write a balanced chemical equation for each of the following reactions and also classify them.
(c) Iron (III) oxide on heating with carbon monoxide gas reacts to form solid iron and liberates carbon dioxide gas.
Iron(III) oxide on heating with carbon monoxide gas reacts to form solid iron and liberates carbon dioxide gas. It is a reaction because carbon monoxide is oxidised, and iron is reduced.
The balanced chemical equation for the statement is
\(Fe_2O_3\) + \(3CO\) → .
2. Balance the following chemical equations and identify the type of chemical reaction.
(c) \(Na\)(s) + \( S\)(s) \(\xrightarrow[]{Fuse}\) \(Na_2S\)(s)
In the above equation, sodium (Na) metal reacts with sulphur (S) to form sodium sulphide (\(Na_2S\)). It is a reaction.
The balanced chemical equation for the statement is
\(2Na\)(s) + \( S\)(s) \(\xrightarrow[]{Fuse}\) .
