Respuesta :

Mg(NO3)2

Mg is +2 in oxidation while NO3 is -1, so you require two NO3 to have a neutral charge: 0

Answer:

Mg(NO3)2

Explanation:

Look at the charges of the cation and anion. Mg has a +2 charge while NO3 has a -1 charge. You’ll need 2 NO3 molecules to cancel the charge of Mg for a neutral compound. This is how they should be balanced unless they give a total charge in the question.
