Question #f8f8f

Answer 1

`2"NO"_ ((g)) + "O"_ (2(g)) -> 2"NO"_ (2(g))`

Explanation:

Nitric oxide, `"NO"`, reacts with oxygen gas to produce nitrogen dioxide, `"NO"_2`, according to the following unbalanced chemical equation

`"NO"_ ((g)) + "O"_ (2(g)) -> "NO"_ (2(g))`

To balance the chemical equation, start by multiplying the nitric oxide by `2` to get

`2"NO"_ ((g)) + "O"_ (2(g)) -> "NO"_ (2(g))`

At this point, you have `2` atoms of nitrogen and `4` atoms of oxygen on the reactants' side and only `1` atom of nitrogen and `2` atoms of oxygen on the products' side, so multiply the nitrogen dioxide by `2` to get the balanced chemical equation

`2"NO"_ ((g)) + "O"_ (2(g)) -> 2"NO"_ (2(g))`
