I said that they discovered the nucleus. Also it is positively charged and contains most of the mass in an atom.
What did you put for the 6 marker?
And what did you get for the bond energy? I got -486

what do you mean
For the energy change question.

I also got 6
Are you talking about the question with the ectothermic graph? I meant the question with the bond energies and you had to look at the table... I'm worried now lmao

At first I did but it couldn't be right as it's bigger, when it had to be smaller I got 3.2 as i didn't double the moles.

The ratio was 1:2 so you had to double the moles

Same i got -486
Did you get 6.4g for the second last one?
