Question

Non-metals are usually poor conductors of heat and electricity. They are non-lustrous, non-sonorous, non-malleable and coloured. Name a non-metal which is required for combustion.

Answer 1

Combustion:-

1. It is basically a high-temperature and redox exothermic reaction, which is also known as burning.
2. There must be burning of fuel and production for the completion of the combustion process.
3. So, for the oxidation of fuel and liberation of heat, a good oxidizer is required which is obviously oxygen.
4. Oxygen will play the role of oxidizer.

Therefore, oxygen is a non-metal which is required for combustion.
