How do you balance Mg+HNO3 -->Mg(NO3)2 + H2?

Answer 1

#Mg + 2HNO_3 -> Mg(NO_3)_2 + H2#

The elements on the left side are: Magnesium (Mg: 1) in elemental form; Hydrogen (H: 2) in two molecules of nitric acid; Nitrogen (N: 2) in two molecules of nitric acid; Oxygen (O: 6) in two molecules of nitric acid each acid has three oxygens, so two molecules of nitric acid are six oxygens.

On the right side, there are: Mg: 1 (one magnesium nitrate molecule with one magnesium atom); H: 2 (hydrogen gas with two hydrogen molecules); N: 2 (one magnesium nitrate molecule with two nitrogen atoms); O: 6 (one magnesium nitrate molecule with six oxygen atoms).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
