@@wbreslyn thank you so much ❤️ Actually I am in class 10th ... Am so nervous.... I have watched your videos on balancing chemical equations u explained so well.... And I subscribed to ur channel.... ❤️❤️ Nice explanation
Evening Dr. B What a very clear explanation between these two. Have been away dealing with a family death. May i ask you to do a quick review on how CO2 gets absorbed bu NaOH? Gas and a base? how? please help. Peace and respect David
Hi David. Sorry to hear about your loss. The rxn between CO2 and NaOH is sort of a big deal since it represents a way to remove CO2 from the atmosphere (e.g. pubs.acs.org/doi/10.1021/es702607w). The CO2 in reacts with water to form H2CO3 (CO2 + H2O ↔ H2CO3). This then reacts with the NaOH (NaOH + H2CO3 = Na2CO3 + H2O See th-cam.com/video/mUiy_5yejMU/w-d-xo.html). So it's sort of a two step process. Actually, this bit on CO2 scrubbing is interesting: en.wikipedia.org/wiki/Carbon_dioxide_scrubber#Sodium_hydroxide Best, Dr. B (aka Wayne)
Hi David. I'm doing a research study on teaching and learning during Covid-19. We're developing the questionnaire and is at the testing phase. Would you be interested in doing a short Zoom call to give some feedback from a teacher's perspective? If so, drop me an email as DrB@Breslyn.org . If not, no problem!
So if an activated carbon filter is a single porous block, then it would be doing both things, absorbs water by capillarity and then adsorbs the dissolved solid into the surface of the pores. I'm still confused, why mark the difference?
There is certainly some merit to that argument! Like many things, often there is more than one thing going on. So it is reasonable to argue that adsorption plays a role, especially in the initial stages of the soaking process, but the dominant mechanism is absorption (the water penetrating into and being distributed throughout the internal structure of the towel fibers).
Thanks❤️❤️❤️❤️❤️❤️
Can u pin my comment
I was looking for this topic..🎉🙏🏻😀
No problem 😊 You've been pinned!

@@Jenniekim789 Glad my videos are helpful! It's okay to be a little bit nervous but not so much it interferes with learning. Thanks for subscribing!
You are the reason why science becomes more easier. I am speechless. Thank you.
Wow, thank you!
That is very clear, and thank you very much ^ ^
Very nice and informative thank you so much
Anytime!
thank you kind sir, you have saved my friend (future CEO of citgo) and me (future CEO of p&G) we will bless you... soon... just wait...
You are most welcome and all the best in your future CEO roles. Don't forget the little people!
I was wondering about this for months
Thanks (and I like your username)!
Ahah someone finally knows about it
It can be very confusing for someone new to the concepts. Thanks for the clear differentiation between the two.
Most welcome!
You are the master sir
I respect you very much
Thank you!
Thank you sir, You've helped me so much with your videos that I was obligated to write this comment of gratitude. 🙏🏻 ❤️
Thanks for the kind words!
Good explanation
Thanks!
thank Dr.B

@@wbreslyn Thank you Dr B...two steps like making Sodium Bicarbonate?
Will check out those links. Many thanks for replying. Peace David

best channel 🐾
I know right
Thanks!
Hii
Thank you
thanks for the video. CO2 INTO WATER: where does the sodium come from ? What type off witchcraft is this?
So if an activated carbon filter is a single porous block, then it would be doing both things, absorbs water by capillarity and then adsorbs the dissolved solid into the surface of the pores.
I'm still confused, why mark the difference?
Thanks a lot .
Most welcome!
Nice video. But I want to argue that paper towel soaking water is adsorption because water attaches onto the fiber(surface).
There is certainly some merit to that argument! Like many things, often there is more than one thing going on. So it is reasonable to argue that adsorption plays a role, especially in the initial stages of the soaking process, but the dominant mechanism is absorption (the water penetrating into and being distributed throughout the internal structure of the towel fibers).
Thanks so much I just want an equation btwn Cu and HNO3 in preparation of Nitrogen 2
Does this help:

I’ve had trouble trying to solve for LaCl3 + Na2CO3 -> La(CO3)3 + NaCl btw all the numbers are exponents. Can you help?
Yeah, the problem is that this reaction isn't possible to balance. The equation you're probably looking for is
LaCl3 + Na2CO3 = La2(CO3)3 + NaCl .
@@wbreslyn oh my bad thanks for the help🙏
thank you!
Most welcome!
First I got confused by the title...then that I realised lol 😂😂
😎
Often, absoption involves chemical reactions, like 2NaOH + CO2 = Na2CO3 + H2O.
Seems like a good way to remove CO2.
paper towel and water? I am not so sure.
Hey what's your name
Sir pls balanced this equation:-SiCl4 + H2O → H4SiO4 + HCl
Thank you
Here you go! Just for you.
