Answer:

Magnesium Nitride - Mg₃N₂

Calcium Chloride - CaCl₂

Explanation:

Magnesium (Mg) has a charge of +2, Nitrogen (N) has a charge of -3.

Swap the charges and you get Mg₃N₂.

Mg: 2(3) = 6

N: -3(2) = -6

The charges cancel out so the formula is correct.

Calcium (Ca) has a charge of +2, Chlorine has a charge of -1.

Swap the charges and you get CaCl₂.

Ca: 2(1) = 2

Cl: -1(2) = -2

The charges cancel out so the formula is correct.

Hope this helps. :)
