Chemistry Worksheet on Naming and Writing Compounds

#### Part 1: Name These Compounds
In this section, we need to determine whether the compound is ionic or molecular. If it is molecular, we use specific codes:
- M: For Binary compounds.
- N: For Nonmetal oxides.
- Q: For Oxyacids.

We will also name the compounds accordingly.
