Question

Balance the following equation: *

1, 1, 1

1, 3, 1

2, 3, 2

1, 3, 2

Answer 1

1,3,2

The coefficient multiplied by the subscript will give you how many atoms of the element there are.

So, if we plug in 1,3,2
There will be 2 Nitrogen and 6 Hydrogen in the reactants side of the equation. To balance this on the other side, we must put a 2 in order to get 2 Nitrogen and 6 Hydrogen again.
