💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

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.

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

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.

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
