Here's what I got.
Explanation:
All you have to do here is identify how many atoms of each element take part in the reaction.
Let's start with the reactants, which as you know are located to the left of the reaction arrow. In your case, you have
#2 xx "N"_ (color(blue)(2)(g)) -># two molecules of nitrogen gas#3 xx "O"_ (color(red)(2)(g)) -># three molecules of oxygen gas
Now, each molecule of nitrogen gas contains
#2 xx [color(blue)(2) xx "N"] = "4 atoms N"# #3 xx [color(red)(2) xx "O"] = "6 atoms O"#
Now focus on the product's side. This side contains
#2 xx "N"_ color(blue)(2)"O"_ (color(red)(3)(g)) -># two molecules of dinitrogen trioxide
As you can see from its chemical formula, each molecule of dinitrogen trioxide contains
#2 xx [color(blue)(2) xx "N"] = "4 atoms N"# #2 xx [color(red)(3) xx "O"] = "6 atoms O"#
And there you have it. Your reaction features
#"4 atoms N " -># on both sides of the equation#"6 atoms O " -># on both sides of the equation
