    I wanna know how this woman helped me in 3 damn minutes when other videos confused me for more than 20 minutes.
    How.

      ikr!! it just clicked I prefer math over chemistry and learning its much like alegebra I'm feeling 10x more confident

      I’m with you. My prof is awesome but he is so intense and speaks as if everything is life and death. “Don’t make the mistake of thinking heat is temperature” “okay? Don’t make that mistake” like whoo, I hope I don’t. This vid was understandable and actually relaxed me.

    I thank God for you, because an hour long chemistry lesson left me confused but you have made it clear to me in 3 minutes, God bless you and all your goals

    Hi Melissa, I am a Biology and Enviro teacher who has been thrown into IBDP Chem for a term to cover the teacher who left. Just wanted to say thanks for the videos. I haven't done much Chemistry for 25 years or so (other than what I need for Bio) so you've been a life saver, particularly with Hess' law. OMG what a nightmare and soooo badly explained in the IB text book and on Kognity. I feel for the students.

  • @lelipstick
    @lelipstick 4 роки тому

    Thank you so much! I can not say how much I appreciate what you do. I've been diagnosed with ADHD and now taking medication to help. But I have my exams in 2 weeks and need to have things explained in a clear manner so it doesn't take up precious time. Your page has been so helpful to me.

  • @themathplanet3071

  • @caseybaranski5230

  • @MrOoglebog
    @MrOoglebog 4 роки тому

    This shows the power of how just slowing down and explaining at a reasonable pace influences how much the student understands. Sometimes quality of explanation is more important than quantity!!!

    Went to my Chem 2 teacher for help, and she overcomplicated it. Three hours with her tutor on campus, still unclear. Watches Khan Academy and study.com videos, still confused. Stumble on this 3 minute video and finally get my first Hess law problem correct on my own. Thank you for simplifying this for all of us non sciency people.

    Hi Melissa, thanks so much for the video i was wondering if you have a video with this problem: 'in all calculations, assume specific heat capacity is the same as water (4.2 J g-1 K-1)
    For both reactions, write full ionic equations and calc enthalpy change for the reaction
    when 25cm3 of 1.0mol dm3 of h2so4 is added to 2.0 mol dm3 Naoh the tempreture rise is 13.0
    If anyone can help me i would appreciate it

    Thanks!

    • @CommonSalt
      @CommonSalt 6 років тому

      I get lost in all the formulas very easily. I just had an exam on calorimetry and enthalpy, and I just cant seem to match the questions with the formulas that I *think* I know. I always feel like there are a million things I need to take into consideration, so I et overwhelmed and just forget everything
