This video has been up for 9 years yet it's still helping students like me who are struggling with chemistry up until now. Thank you so much for this!
thank you very much - the MINHO order was new for me but much more helpful than the way they teach it in the textbooks.
Super helpful!
If Poly atomic group is not on the product side then how to solve !?? Please mam reply 🙏🏻

😌
Could you show us a scenario where you have to multiply the numbers?
Good video, but in the very end, 3S should be the same height as 3P though, both have 2 electrons each.
Thank you mam
❤😂thank you!!! teacher
Great video, my science teacher never taught this to me so thanks heaps!
damn, didn't think Kpop would help me study. Minho?? any stays taking chem????
I literally love this video, im revising for a chemistry test and this has helped me so much, thank you!!!
you're teaching wrong tf, the students watched this video will be wrong too
the order reminds me of my love Min ho from XO Kitty. This will make it easier to learn. Thanks a lot
genuinely one of the best videos after searching through the textbook and even khan academy. made these types of problems so much easier for my final! thank you so much ur wonderful.
she's teaching the wrong way, the polyatomic reactants is 9, whereas the product polyatomic 12
Really clear👍
fantastic video !
Thanks Denise, this cleared things up
so would that mean the the enzyme that cut it would be at around 1411 bp on the circle
good questions
Thank you so much
This was such a clear explanation thank u sm!!
Wait, so.. *CO3* = 1 CO3 and not 3 CO…
Thank you, thank you, thank you
This video is such a gem, thank you!
Thank you so much this was so helpful
Thank you! great video..
Thank you so much for making this video!
Thank you Denise Sanders
Very nicely and simply explained...thank you
Keep it up
Where are you from
Are you die now
what about for NH₃+H₂SO₄ = (NH₄)₂SO₄
after this video i love u so much u saved me alot of time and effort
tysm for your help 😁
VERY HELPFUL THANK YOU SO MUCH
Even almost 7 years later this proves more useful than a 90 minute lecture in university. I thank you so much for this video!
what if your trying to balance extremely complex equations this is extremely simple to what im trying to balance atm where the carbon atoms hydrogen atoms and oxygen atoms arent the same number on either side, should i start by balancing the oxygen then hydrogen then carbon or? what would be the easiest order
Nice this is exactly the information I was looking for. Thanks!
Very helpful, thanks
Tysm you helped me :)
great video cuh
Thank you!
I just had a test where we were told to balance: Cu2S + HNO3 = S + NO2 + Cu(NO3)2 + H20. How do you balance this when you have NO3 on the left side, but NO2 AND NO3 on the product side? I tried to split the N`s and O`s, and I got more confused since the numbers really never went up by multiplying. I constantly had to change the coefficients.
How about this, I know I am late, your idea was fine, but be patient always. Take its as Nitrogen and Oxygen separately. Cu2S + 8HNO3 = S + 4NO2 + 2Cu (NO3)2 +4 H2O. Cu = 2 Cu = 2 S = 1 S = 1 H = 8 H = 8 N = 8 N = 8 O = 24 O = 24
Tq
helped with my homework👍
I couldn't get it to work for Zn + HNO3 -> Zn(NO3)2 + NH4NO3 + H2O in my final answer oxygen didn't get balanced
thank you mam
Thank You! 🙂
