Question

Metal oxides react with non-metal oxide to form a salts. Explain with example of a balanced chemical reaction.

Answer 1

Reaction between a metal oxide and non-metal oxide:

• Metal oxides are commonly basic in nature and non-metal oxides are acidic in nature.
• When a metal oxide reacts with non-metal oxide, they both neutralize each other resulting in the formation of a salt.
• Example: When a metallic oxide (Calcium oxide) reacts with non-metallic oxide (carbon dioxide), leading to the formation of Calcium carbonate.
• The balanced chemical reaction can be represented as:

$$\begin{gathered} \mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)\to {\mathrm{CaCO}}_3\left(\mathrm{s}\right) \\ (\mathrm{Calcium}\mathrm{oxide})(\mathrm{Carbon}\mathrm{dioxide})(\mathrm{Calcium}\mathrm{carbonate}) \end{gathered}$$
