Calculate the total positive charge present on the positive radicals in the following compounds:
Magnesium nitrate

Explanation

To calculate the total positive charge present on the positive radicals in magnesium nitrate, follow these steps:

### Step 1: Identify the Components of Magnesium Nitrate
Magnesium nitrate consists of magnesium ions and nitrate ions. The chemical formula for magnesium nitrate is Mg(NO₃)₂.

### Step 2: Determine the Charges on the Ions
- **Magnesium Ion (Mg²⁺)**: The charge on the magnesium ion is +2.
- **Nitrate Ion (NO₃⁻)**: The charge on each nitrate ion is -1. Since there are two nitrate ions in the formula, the total negative charge contributed by the nitrate ions is -2.
