The correct formula for magnesium nitrate?
Question 12 options:

MgNO3

Mg2NO3

Mg(NO3)2

Mg2(NO3)2

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.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
