    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

      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 года назад +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.

      no, he is right!! , whenever something reacts in Water if its endothermic( it absorbs Energy special case a salt in Water: the lattice Energy is higher than the Hydration energy) the Water has to give Energy (heat) to Reaction, so it will make the Water cold( Water gave heat , so Exothermic) the Reactant absorbed Energy so Endothermic!

      And this. What is the specific heat of water in kJ kg K?
      4.187 kJ/kgK
      Specific heat (Cp) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)

    I don't know if this is too late but for the problem asking for the enthalpy change why wouldn't you add the mols of CaCl2 and H2O? You're finding the enthalpy change for when CaCL2 dissolves in water so why leave the mols of the water out?

    Are the units in the last question joules or joules per minute?
