What are the Half-Reactions?

[@imjustczarina]

I don't know why, but I can understand you're explanation better than anyone's...AND you really has a nice sense of humor!

[@juliaa3232]

This is awesome man! Learnt more in this video than in all of my classes, such a clear explanation.

[@nickcolejackson6884]

Thank You for helping me to understand oxidation numbers. I really understand the concepts that you discussed I wish you were my professor in beginning chemistry because I understand more now than I ever had before. I am in Quantitative Chemical Analysis. For those who are listening to him and are going to upper level chemistry courses, these concepts are much needed, so, PLEASE understand them fully because they WILL!!!! show up AGAIN AND AGAIN!!!

you fucking hillbilly

[@hihellohi1234567]

Excellent video! After watching 3 vids on how to do this, THIS video FINALLY explained it in a way that I understood! :)

[@ShooMoo]

I would not have learned this without you. Thanks!

[@bluetrolling]

I wish you were my teacher! Mine keeps making mistakes and makes it confusing...so thank you very much for making these videos. It is greatly appreciated! : )

[@bhiesshhhhh7867]

you just helped me pass my 4th year.

[@alexalder2600]

do you do redox reactions in 12th grade? and are you in america?

[@fredydeekrueger169]

Great video! Used this for a quick review before my exam.

[@dulcerubio4258]

Thank You! I have been struggling with this topic for days. You have explained it so clearly, and I finally get it now. New subscriber (:

[@RXLIFTSZ]

Got a chem test in like 10 mins watchin this before wish me luck every1🙏🏽

[@DALERKHUJAND]

i want to put 100000000000 likes for this video, but unfortunately youtube only lets me to like it ONE time. GREAT EXPLANATION.

[@anthonyn9096]

ty u explained sooo well.

[@s.muneeba3944]

Why didn't you write the half equation of Mg starting with Mg? Why did you ignore the 2 in 2Mg (not talking about the compond. I'm talking about the lone element) Is it a rule? I only ask.. because I have a bit of a doubt in one question. 4Fe+3O2 -> 2Fe2O3. we need to make half equations on this and I got this answer 4Fe -> 2Fe2 + 3e- 3O2 + 2e- -> 2O3 It's wrong. and I don't understand why. Helppp

[@jackryder5073]

This helped me a lot

[@Maria-jy9cm]

thank you so much!

[@coryphillips1783]

You say the S ion has -2 but it doesn't show it on there

[@JustBeFancy]

THANKS!

[@JS-vo6go]

why is Cu 0 if there is a +1 right next to it?

[@mutigandafaustin1390]

are there spectator ion(s) ?

[@aaronrobles9875]

nice videos. thanks dawg

[@CoolKid-op9kq]

why was copper +2 ?

[@hesampishnamazi2636]

Thanks a lot! you're great!

[@jetstar7051]

what accent does this guy have? (i know totally unrelated but still)

[@limehalo5566]

I think its canadian maybe because the way he says the word out sounds like it.

[@davidrottschafer7974]

2:26 Canadian, the way he says "Without"

[@hindinetwork8722]

i dont understand how u bring +3 al and cu +2

[@nicolasbello1484]

+zakhmi marzaki If you look at your periodic table and check a(n) element, they will have oxidation states such as -2 or +4. Some elements like Manganese will have multiple oxidation states that are positive so depending on what other element its paired with like Oxide (which has a oxidation state of -2) than manganese will be +2 to cancel out the oxidation to be equal. You should know this due to the attraction between Cations and Anions. And be careful with elements that have both charges on it's oxidation state like Sulfur which has both charges so if its paired with a element thats a negative it will be positive and vice versa. So thats how he got +3 for Al since it has an oxidation state of +3.

[@goodbad665]

2Cr3+ does it means 6e- ?? Thx

[@madelynfernandez9173]

yes

[@ovocow9512]

Shouldn't Cu+ have an oxidation state of +1?

[@9408lino]

OVO Cow Its not Cu+ its Cu + Al2(SO4)3 The plus sign was just written too high.

[@ovocow9512]

Good catch! Thanks bruh!

[@Enchilada_Angel]

Gracias !

[@preetirawat1619]

Thanku .....sir....

[@Syvmana]

Vielen danke!

[@stub5413]

cool

[@mrsshayful]

your voice sounds like john ritter, its a little distracting.

[@coryphillips1783]

Nothing makes sense. Sounds like Vietnamese

[@AiKichune]

I HAVE BEEN SITTING IN MY CHEMISTRY CLASS SINCE 2014 WITH SO MANY QUESTIONS AND YOUR VIDEOS ARE JUST GENIUS TuT!!! THANK YOU~~!! ////;A; I wish you were my Chemistry teacher!//
