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. :)
