So, I had my exams a few days ago, and I wrote the following reaction:



Crappy handwriting, but tell me is that wrong?
Can't we write like that?

It is crikey.

Well, you seem to have lost the H2SO4 catalyst from the right hand side of the equation...

Poor Johnny had studied chemistry

   But he should have studied more.

What he thought was H20

   Was H2SO4!
Why? Water does come out of the reaction, this is one of the reasons H2SO4 is used (the other, main reason is to form the nitronium ion NO2+).

Ah yes.
H2SO4 does come out at the end. Apparently I didn't see it, but in general let us ignore it, and imagine that H2SO4 is written on top of the arrow!

Now, are there any answers?

Given that the H2SO4 is written in in such a way as to indicate that it's catalyst and not reagent, I can't see anything else wrong.
I'm not sure what your question is... did you get marked down for putting that as an answer? If so can you tell us the exact wording of the question (if an answer isn't in itself wrong, but is none-the-less marked down, it's often worth checking it isn't just the wrong answer for the question posed).

To the fact you shoudn't have written the resonance in nitrobenzene? I don't see any mistake, I would have written the resonance too.
