Question

with the help of an example explain what happens when a base reacts with a non metallic oxide what do you infer about the nature of non metal oxide

Answer 1

when a base reacts with a non metallic oxide, it forms salt and water.thus non metallic oxides are acidic
Eg:
Ca(OH)2 + CO2 --------> CaCO3 + H2O

Answer 2

When a 'base' reacts with a non-metallic oxide, it forms a salt and water.

EXPLANATION:

For example, 'calcium hydroxide' reacts with carbon dioxide to form 'calcium carbonate' which is a salt and water. The chemical equation for the reaction is:

$\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{CO}_{2} \rightarrow \mathrm{CaCO}_{3}+\mathrm{H}_{2} \mathrm{O}$

It can be inferred that "non-metallic oxides" are 'acidic' in nature and therefore react with bases like acids do to form 'salt' and 'water'. The reaction of bases with non-metallic oxides can be complex in nature.
