    My teacher is typically good at teaching chem stuff, but for some reason I just can't understand this unit, even when she goes over everything. I tried asking her for extra help but she gave me a really vague answer for some reason and then just said I was getting too distracted (despite immediately coming up with actual times for other students who asked, including my friend who sits right next to me and is equally distracted). But besides that, thank you so much for this video (and entire channel). It always helps me whenever I don't know what to do.

    • @harishnathan4011
      @harishnathan4011 6 років тому +3

      Endothermic means that the reaction gained heat and so the temperature of the solution would increase.
      Exothermic means that the reaction lost heat and so the temperature of the solution would decrease.

    • @wave1218
      @wave1218 4 роки тому +1

      For you in two years ago. I think its his error he made. He supposed to say "by anytime the temperature of the solution goes up that tells you the reaction is EXOthermic, if the temperature of the solution went down the reaction would be endothermic"
      Furthermore, If the temperature of the solution increase, the reaction must release energy so its exothermic in order to raise the temperature for the water, thus, the water absorbs heat which become endothermic for the water.

      Hi Kai! I just want to make a correction to your point as this can confuse other students. So, The Tutor is actually correct. It is 54266.7 and not 54131.
      The thing is you rounded off 1.333333 into 1.33. As you can observe, he calculated it straight without rounding off 1.33. No hate please.
      In short,
      (1.3333333)(40.7)(1000)=54266.7J
