      True, in my opinion, teachers and professors take that long on purpose like they could have finished earlier, but they decide to finish nearly at the exact time because of institutional guidelines that they have to follow including the pay per hour rule.

      I feel the same, but you gotta remember that repetition is key to remembrance. Maybe your professed layed the groundwork by exposing it to you and this vid help build upon it? Or maybe they're just bad professors haha

    @michellwaterman3160 2 года назад +6

    I appreciate that you take the time to solve the equations without using a calculator. My chemistry professor isn’t that cruel, but my calculus professor IS. All these little tricks to combining very large numbers without a calculator has been a lifesaver! You and Professor Leonard have gotten me through my last semester as an undergrad.

  • @AK-op4be
    @AK-op4be 2 года назад +11

    Chemistry is sooo much info, first you need to learn all the vocab & understand whats going on, then memorize the equations to finally be able to do the practice problems 💀 but atleast if i dont learn from my prof, I can learn from other teachers on youtube like this one.

  • @cassandra-lynnecowley6475
    @cassandra-lynnecowley6475 6 лет назад +20

    Just an FYI for you, towards the end of your video when you have the equation (-393) + 2(-286) - (-785) ..... You calculated that 2*-286 was 576.. but it is actually 572. which would make the actual answer to the equation be 180. just thought i would mention.... LOVED the video though, really helped me better understand.. I have a midterm on Saturday .. here to hoping I pass.

  • @GSU_Panther_Nation
    @GSU_Panther_Nation Год назад +1

    You teach better than the text. Soon, teachers and professors of chemistry will surely enough begin jumping onboard to your channel for quality lecture content, only for the teacher/professor to work out a few example practice questions on the board for the remainder of class

    Just wanted to let you know. When doing total standard enthalpy change for a reaction, the final units are kJ not kJ/mol since you are multiplying by moles.

    • @loooongstory

      This is really important because units are a tell tale sign of whether you’re doing the calculations right or not.

  • @quincyzhang299
    @quincyzhang299 4 года назад +1

    18:38, the enthalpy of the reaction should be -184 kJ/mol. The mistake occurred at -286 times 2, should equal to -572 instead of -576.

    On your problem: CH4 + 2O2 -----> CO2 + H2O, the answer is -180. I think you miscalculated 2(-286) to be -576, instead of -572.
