    18:00 Please correct me if I may be incorrect here: This is for the solid compounds but the notion is identical for others! ∆H atomization = - ∆H (fusion) + ∆H (vaporization) + ∆H (bond dissociation)

    do u have any revision tips? my exams are in two months and i feel SO lost as my method is just trying to memorise everything

    The best advice I can give you is to do past papers. Mark them yourself, revise the topics that you couldn't answer, and take more papers. Keep repeating this and keep filling in the gaps. It's tempting to make notes/flash cards on topics that you already understand well, but this would be a waste of time. Best of luck!
