Can a non metal reacts with gas?

Yes, a non-metal can react with a gas. For example, non-metals such as sulfur and oxygen can react with gases such as hydrogen to form compounds like hydrogen sulfide and water. These reactions typically involve the sharing or transfer of electrons between the non-metal and the gas molecule.

Yes, non-metals can react with gases. For example, sulfur reacts with oxygen gas to form sulfur dioxide, a gas. The reaction is:

```
S + O2 → SO2
