Question

Can someone help me on this please ?

Answer 1

Answer:

1. Each of the above compounds have two different elements.

2. The elements are non-metals.

3. The name carbon monoxide cannot be used for the first two compounds because CO contains one atom of oxygen, hence it is named carbon monoxide. CO2 contains two atoms of oxygen. Hence, it is named as carbon dioxide.

4. We can see that each atom is named according to the number of atoms of the element present in the compound. For example, Phosphorus trioxide is named so because it contains a single atom of phosphorus and three atoms of oxygen.
