Write the chemical names of the following compounds.
`K_2MnO_4`

Explanation

To write the chemical name of the compound \( K_2MnO_4 \), we can follow these steps:

### Step 1: Identify the components of the compound
The compound \( K_2MnO_4 \) consists of three elements: potassium (K), manganese (Mn), and oxygen (O).

### Step 2: Determine the oxidation states
- Potassium (K) has an oxidation state of +1.
- Manganese (Mn) in \( K_2MnO_4 \) has an oxidation state of +6. This can be determined by knowing that the overall charge of the compound is neutral and that each oxygen (O) has an oxidation state of -2.
