The decomposition of dinitrogen tetraoxide into nitrogen gas and oxygen gas is shown by which balanced chemical equation?

So dinitrogen tetraoxide is N₂O₄ and nitrogen gas is just N₂ and Oxygen gas is O₂.

So on the left side you have 2 of nitrogens and on the right you have 2 nitrogens so that is already balanced...

But on the left you have 4 oxygens and on the right you have 2 oxygens, so you need to multiply the right oxygens by 2 to get 4 on both sides.

So overall, I believe, the balanced equation would be N₂O₄ ⇒ N₂ + 2O₂

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
