How to Balance Half Reactions

[@thegloriousdesigns5736]

Your channel is amazing! Whenever I need help with chemistry, I always come here because I find the answers I'm looking for.😊

[@cae7514]

Man, I love your channel, I'm studying chemistry and every time I have a question I search your channel and you always have a video for everything, thank you very much!

[@wbreslyn]

Thanks, that is motivating for me to hear!

[@rakiamohammady4747]

Same here

[@lightcapmath2777]

Evening Dr.B. I just finished working such Q's for a student. Having watching this vid before our session, was able to give clear and numerical clarity to answer all correctly. DVD...U Rock! Dr. B :)

[@wbreslyn]

Great to hear David! I'm pretty proud of this redox resource, it took me forever to research and build but it's one of those topics that students struggle with. Glad you found it helpful!

[@balan4774]

I felt its neccesary for me to say, I have been watching your videos during doubts and topics in exam for past 5 to 6 years, I am writing my final chemistry 12th exam today. thank you for being such an amazing teacher.

[@wbreslyn]

Thank you for commenting, that is very motivating for me to hear. All the best on your chemistry exam today!

[@vrks6799]

Thank you so much for this video!! I have a midterm tomorrow and this cleared up so many of my confusions

[@Marykiu]

Perfect! I'm so happy that I've found your really great channel. Thank you so very much. 😊 Now, I understand how "redox" works!

[@elmatochannel3756]

One of the best channels I´ve been learning from. Great!. Thanks Dr.

[@wbreslyn]

You are most welcome!

[@KSATSpotting]

Im majoring in Chemistry and even though you said it's hard (it kinda is) your explainers make it seem elementary. Thank you!!

[@homosubi]

Dr.B,you are a great Teacher.I've been learning a lot from you and will continue to learn more👍🏻

[@wbreslyn]

I appreciate that!

[@cartoonfan5449]

Hello Sir Can you please make a video on When Fe shows 2 and 3 valency ?

[@D0rlisok]

you saved me. thank you so much

[@damanbains7640]

Dr B you are the best

[@Sunset.1235]

Hello , Dr. B, your video is very informative and Clear, thank you for breaking it down in simpler steps. Just one question please, where did the -5 come from? 6:50

[@ravikumark3910]

Namaste sir! I'm from India your teachings helped me a lot and btw why don't u make teachings on organic chemistry from basics, if u do such videos , it helps a lot of students like me. I'm really grateful for your teachings.😊

[@wbreslyn]

I've been thinking about doing a series on organic chem, maybe in the near future!

[@Kookaburrra]

I'm pretty sure you will be helpful in my future days

[@wbreslyn]

Excellent!

[@shwiniB]

Thank you sir 👍

[@wbreslyn]

Welcome!

[@thelastclasher7417]

keep doing what you are doing! You are a great teacher! Ochem up next for me! 🤓

[@wbreslyn]

Thank you! I've actually just started working on a series of guides for ochem. Should be up on www.breslyn.org in a month or so.

[@thelastclasher7417]

I'll take a look soon ! Thanks

[@extralives8693]

Sir, can we use oxidation and reduction with defination of addition and reduction of electronegative /positive ions?

[@wbreslyn]

Oxidation and reduction [provides a fundamental framework for analyzing and predicting the outcomes of chemical reactions involving the transfer of electrons. So what you say makes sense.

[@happymck4641]

Dr.B, do you follow ap chem courses (like the time they teach everything)? I feel like you know what's going on in my class everyday lol.

[@wbreslyn]

That is great to hear! Yes, many of the topics follow AP and by extension gen chem in college.

[@alcondones5691]

Thanks 😊

[@wbreslyn]

Welcome 😊

[@meenahb976]

Can you please give me tips to study chemistry quickly Because I have a big exam in few days

[@wbreslyn]

Pace yourself and focus on areas where you feel you are weak. Don't just study the stuff you already know! And do as many practice problems as possible. That's my advice a few days out from a big exam. All the best on your exam!

[@XitLofi]

Dear sir, My Name is Purushottam I have an little doubt, What's difference between MINIMUM & MAXIMUM ?

[@wbreslyn]

Hello Purushottam! The difference between minimum and maximum is about the lowest and highest amounts or degrees permissible or possible, respectively. In a marathon, the minimum time is the fastest pace at which a runner completes the race, while the maximum time is the slowest pace allowed before the race officially ends.

[@thegloriousdesigns5736]

Can you please tell me that how to write this statement (carbon+hydrogen+oxygen➡sugar) in a balanced chemical equation? I am unable to find it anywhere😞

[@wbreslyn]

I'm not sure of the equation for just C + H2 + O2 = sugar. Perhaps take the C + O2 to make CO2. And the H2 and O2 to make H2O. From there photosynthesis would be able to create glucose. This might help kzbin.info/www/bejne/o3jFc2eoapulgqc .

[@DeepshikhaBhandari-g7g]

Please tell where you balance chemical equation😢 please...

[@wbreslyn]

We usually balance the atoms in the half reactions before we balance electrons (or the H and O atoms).

[@meerasamant7]

bro i promise when i grow up pls make livestreams ill donate a lot

[@meerasamant7]

u used to get so many views and likes what happened

[@wbreslyn]

Most of my stuff takes a while to get into the search engines and such. So overall on my channel I'm getting more views but new videos seem to take longer to gain traction. Sometimes several months, but then the do well enough!

[@Marykiu]

Thank you so much. GREAT! 😊I can use these steps for the many redox reactions I have done till now and it works perfectly. I only can't solve this reaction "Hgo -> O2 + Hg" by using the same steps . Can you please tell me if I'm wrong? 😢

[@wbreslyn]

You are welcome, that is great to hear! Sorry for the late reply but you might try putting the equation in here: www.periodni.com/half-reaction_method.php That'll show you the steps.

[@JemimaOreofeoluwa]

I don't understand how you balanced Carbon

[@wbreslyn]

This is the full video for that redox equation: kzbin.info/www/bejne/b5Kyi2WBbp10jaM That should help.

[@Indian-357]

How many languages can you speak?

[@wbreslyn]

That's an interesting question. On my own, English, Spanish, some Twi and Kusaal. But with the assistance of technology I'm able to communicate across most languages. I try to do that on my channel when I reply to comments and it may create a perception that I speak more languages, unaided, than I really do!

[@Indian-357]

​@@wbreslynI have never heard of twi and kusaal

[@Indian-357]

​@@wbreslynNo esperaba que hablaras español.

[@DarkPrincess_M]

Dr.B, Which one is more electronegative 1) Nitrogen 2) Chlorine Explain in detail please(different sites show different answers so I'mma bit confused🫤)

[@wbreslyn]

This might help: kzbin.info/www/bejne/oGjPkpyHlpd-eqc

[@DarkPrincess_M]

@@wbreslyn the chart shows cl is more electronegative but shouldn't nitrogen be the one?
