The difference in marker colors, hand direction, clear speech, organization and thorough explanations help a ton when trying to understand. Great video.
I paused the video at the very beginning to try to solve it on my own... Thank you very much Mr. DeWitt, using the clear step-by-step explanation from the previous video on this playlist I managed to solve the problem by myself.
Salima Naj totally totally totally agree - I've just had a 2 hr lecture and I was completely lost - I listen to Tyler for 15 mins and gosh it all makes perfect sense. Thank u Tyler - Chemgod
well at first i was like youre going waaaaaay to slow but i sat through this after not understanding this concept for awhile now and badabing badaboom i understand it THANKS!!!!
I am seriously thinking of giving up school and just learn off RU-vid. How can you explain something that took my lecturer 3 freaking hours to do in less that 15 minutes. Even the lecturer got confused midway through the lecture, ol' man gave up!!!. In conclusion: Thank you for making these very useful videos. They make me sane while studying. Please, do not stop.
I really want to thank you, i have a honors chemistry final tomorrow and you have videos for every topic that is going to be on the final, and i understand everything, your methods are amazing and you actually make it interesting to learn, so thank you. (:
I cant believe I just found the best explanation ever!!!!!! I've been struggling with this alot and your video has helped me.(this video was posted 7 years ago😭)
Thank you so so much Mr Tyler i was unable to solve these redox reactions and now I'm super genius at solving these stuff. You're heavenly sent person♥️
My teacher uses a similar example with the Cr2O7^-2. But he says to use Cr2=+12 opposed to this video which uses Cr=+6. This changes the balancing of electrons in the next step. So which one is right? And how do I know which one to use?
I love the fact that it makes you smile when you do chemistry. keep up the beautiful teaching man bravo! p.s when you smile i laugh and then i get more energy to study ((:
Thank you so much, I have watched other videos of redox and half reaction tutorials but never have I ever found a tutorial as easy and simple to understand as yours. I am very grateful for your videos :)
I actually searched this to see balancing for charges which was not clearly mentioned in the study material. But you can teach really well my chemistry teachers also teach in the same way but I unfortunately missed this chapter so video helped me a lot. Thanks!
Im done with chemistry, and damn I can still watch your videos because you are soooo good. I wish you were around when I had high school chemistry. Your videos helped me my college chemistry.
hi sir, may I ask when writing the half reaction for oxidation and reduction reactions, why didn't we write the addition of electrons within the equation? like for example, the +e^-
Dewitt whenever I watch you , I just feel You are awesome! Where are you now and what's you doing??? These are some of the obvious questions your students wanna know
I was just wondering whether we could figure out what compounds were being oxidised and what were being reduced just by looking at the equation. I mean like if one compound on the reactant side had oxygen in it and on the product side the oxygen was not there, then couldn't we just realise that the compound was being reduced. Then we could technically skip the calculating of oxidation numbers step right? or is this not always the case?
The oxidation number of the higher atomic number halogens (chlorine, Cl, Bromine, Br, and iodine, I) is usually -1. Should not Iodine be -1 instead of the zero you assigned it?
Very helpful, but can you not hold your hands over the words when you're just talking and not pointing at anything? I can't take notes when your hands are being held over them and it's really distracted.
