    Can you do a tricky hess law question where they give you enthalpy changes of combustion but want you to calculate enthalpy change of formation please

    wait can you write it like that or does it have to be in full sentences? I thought the quality of written communication meant u had to write fully?!

      MS says ‘There is a well-developed line of reasoning which is clear and logically structured’
      I’m no exam marker but I’d say the answer I give is all of the above.
      Writing a fuller answer runs the risk of running out of time. That’s the last thing you want to do!

    why is the overall rate change 1? Am I just being dumb

      @curry-xy4og Месяц назад

      if a rate doesn't change its the same as saying something increases by x1 if I have 5 carrots and after a day I still have 5 carrots its an increase of x1 if that makes sense
