Question #69d7d

Answer 1

`3"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))`

Explanation:

Magnesium will react with nitrogen gas to produce magnesium nitride, `"Mg"_3"N"_2`, and ionic compound that consists of magnesium cations, `"Mg"^(2+)`, and nitride anions, `"N"^(3-)`.

The unbalanced chemical equation looks like this

`"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))`

Notice that all you need to do in order to balance this chemical equation is multiply magnesium metal by `3`. This will give you a total of `3` atoms of magnesium and `2` atoms of nitrogen on both sides of the equation.

`3"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))`

This reaction is an example of a redox reaction. Here magnesium is being oxidized and nitrogen gas is being reduced.
