    To all the Year 11s close to doing their exams, I wish the best of luck to all of you. make sure you revise at least 1 hour on a subject a day. I did this and imagined to pass my science English maths business it and engineering. you will all accomplish great things in life if you work hard for it.

      You don't have to revise an hour for every subject that's around 6 hours of revising a day for all subjects, that's far too much I only revised a few hours and managed to get 9s. Work smarter, not harder.

    Why did you flip the sign of the -74.0 KJmol-1?

    • @Freesciencelessons
      @Freesciencelessons  3 роки тому +9

      Because the arrow pointed in the wrong direction so we needed to reverse the sign.
