Question

Name non-metal which is required for combustion.

Answer 1

Answer:

Combustion:

• Combustion is a process in which a substance burns in the presence of Oxygen$\left({\mathrm{O}}_2\right)$, and provides heat and light.
• A non-metal Oxygen is always required for combustion.

For example, Burning of Coal or wood for the household purposes:

$$\begin{gathered} \mathrm{C}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{CO}}_2\left(\mathrm{g}\right) \\ \mathrm{Coal}\mathrm{Oxygen}\mathrm{Carbon}\mathrm{dioxide} \end{gathered}$$

Conclusion:

Therefore, Oxygen$\left({\mathrm{O}}_2\right)$ is a non-metal which is required for combustion.
