Answer 2

Writing Molecules Using Chemical Symbols

To write the molecules of nitrogen and nitrogen dioxide using chemical symbols, you can use the following representations:

- Nitrogen Molecule (N2): The molecule of nitrogen is represented by the chemical symbol "N" for nitrogen, and since there are two nitrogen atoms bonded together, it is denoted as "N2".

- Nitrogen Dioxide Molecule (NO2): The molecule of nitrogen dioxide is represented by the chemical symbols "N" for nitrogen and "O" for oxygen. It consists of one nitrogen atom and two oxygen atoms, so it is denoted as "NO2".

These representations are commonly used in chemistry to denote the composition of molecules using chemical symbols.
