Question

What type of oxides are formed when non-metals react with oxygen? Explain with an example.

Answer 1

Oxides:

• “The binary compounds formed by the reaction of other elements with oxygen are called oxides.”
• They are classified as acidic oxides, basic oxides, amphoteric oxides and neutral oxides.

Reaction of non-metals with oxygen:

• The reaction of non-metals with oxygen results in the formation of acidic or neutral oxides.
• For example, the reaction of Carbon ($\mathrm{C}$) with Oxygen (${\mathrm{O}}_2$) gives Carbon dioxide (${\mathrm{CO}}_2$) which is an acidic oxide. On the other hand, Hydrogen (${\mathrm{H}}_2$) reacts with Oxygen (${\mathrm{O}}_2$) to give water.

$$\begin{gathered} \mathrm{C}\left(s\right)+{\mathrm{O}}_2\left(g\right)\to {\mathrm{CO}}_2\left(g\right) \\ {\mathrm{H}}_2\left(g\right)+{\mathrm{O}}_2\left(g\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(l\right) \end{gathered}$$
