So this question asks us to write the unbalanced equations for some reactions.
00:06
So part a asks for nitrogen and oxygen reacts to form nitrogen dioxide.
00:12
Will we know that on the left side we have nitrogen and oxygen, but because these are gases, they will be in their diatomic form as such.
00:23
On the right side, we have nitrogen dioxide, and that die prefix on the oxide, case that there's two.
00:34
So that's what the unbalanced equation looks like.
00:38
Part b, di -nitrogen pentoxide reacts to form di -nitrogen tetroxide and oxygen.
00:44
So di -nitrogen pentoxide.
00:46
So dye means two, so there's two nitrogen in that compound, and pent means five, so that there's five oxygen.
00:53
And that reacts to form dinitrogen tetroxite, so we have two nitrogen, just like before, and then the prefix tete means four.
01:05
It's a four oxygen.
01:08
That forms oxygen.
01:12
And because it is a gas, it is in its diatomic form.
01:16
Next, we have ozone reacts to form oxygen.
01:20
Well, ozone is 03...
