Write the names of the following compounds : `H_(2)S, CO, N_(2)O_(4)` and `PCl_(5)`.

Explanation

To write the names of the given compounds \( H_2S, CO, N_2O_4, \) and \( PCl_5 \), we will follow these steps:

### Step 1: Identify the elements in each compound
- For \( H_2S \): The elements are Hydrogen (H) and Sulfur (S).
- For \( CO \): The elements are Carbon (C) and Oxygen (O).
- For \( N_2O_4 \): The elements are Nitrogen (N) and Oxygen (O).
- For \( PCl_5 \): The elements are Phosphorus (P) and Chlorine (Cl).
