I swear I prayed to god to actually bring those videos infornt of me on YT that will clear my concepts and doubts I always had and this video damnnn dont know why didnt it ever came in fornt of me whenever I searched exo endo Topic. I have my medschool entrance exam in 10days . Need prayers guys , Peace
Thời giờ , vibration , điện lực , và dung tích liên hệ trực tiếp với nhau...time vibration , electricity , volume related directly ...translate vibration into mathematics formula base on letter á variable then it open your mind
Bravo good sir. I wish and bless you with immunity for the current and ongoing coronavirus pandemic, because I want to be able pass my open university degree.
Your videos are helping me understand basic chemistry better than my class textbook! My instructor is of little help because my class is online, therefore, I absolutely rely on chemistry videos to understand this stuff. So... thank you!!!
this was so helpful thanks soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo much
This is the easiest topic in Chemistry and i don't understand it hoow the fvck will i understand other topics ??🙂 And after some months i have IGCSE Exams 🙂💔💔💔

I believe greatest way to "understand" a subject is to teach based off what we are already familiar with in real life. For instance, The Organic Chemistry Tutor uses real-life examples which are already well-known to us, while many teachers explain in scientific ways, such as providing new formulas, bunch of variables and using scientific terms. In addition, some teachers don't pause to make sure to let students try some practice problems and catch up to the teachers' explanations. The run-ons is also what really frustrates many students, including myself. I am really glad The Organic Chemistry Tutor is helping us out here
9:45 - the rule of bond formation Being exothermic is in direct contrast to the rule of organic compound synthesis (eg. fatty acid formation) being endothermic. What is one-sentence key reason for the difference?
Can you please answer my question? With these diagrams, do they show enthalpy or purely potential chemical energy? My confusion arises from the following: In an exothermic reaction, we know that chemical potential energy decreases and for conservation of energy to hold, kinetic energy should rise (product molecules moving faster). But if we said enthalpy decreases there will be a contradiction because enthalpy is internal energy + PV (assuming PV change to be zero) , internal energy ITSELF contains kinetic energy of the molecules, so how could overall enthalpy decrease (KE increases and potential energy decreases by the same amount)
No need to overthink this here is nothing to do with the kinetic energy .Since the chemical potential energy decreases it means nothing with respect to kinetic.The lost energy goes to outside surrounding
it is endothermic because cl- ions are unstable in comparison to when they are in bond state. So when heat is given to them they become highly energies and break into ions. That's why they are endothermic.
you are an amazing person and the only reason im acing my school exams in collage right now is cos of these videos, i would not even be passing my test if it weren't for you so THANK YOU A LOT!!
You are a true saver! Your work is excellent and your teaching skills are awesome. Thank you so very much for all that you do--Chemistry works!! Ever-lasting teaching and all Gratitude for your good works.
Thank you so much, everything you explained very clear. The first time I got your Chanel, so I already subscribed. I like the way you explain. It was very hard to understand but I got it after watching your video. Thanks.
from 10:44, I guess you were wrong all those reaction you mentioned are endothermic not exothermic, and thus they should me ΔH positive. Tell me if I'm wrong.
