Chemistry on Khan Academy: Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

This was exceptional. Thank you. Why couldn't my professor have explained it like this!
Wonderful! Thanks guys.
Thank you VERY MUCH!
Very clear explanation but the audio seems to be very low.

Ya....
Yes i have full volume, but hard to hear
audio is loud and clear , but he may talk to fast for non-first-american-speakers who are relatively new to this. I would recommend to him to SPEED UP the writing the way others do, but slow down your audio #youcanlearnanything. Pitch and emphasis are great. Color choices are great. A grade :)
Excellent explanation sir. Sir can u plz make a video on hydrolysis of amphiprotic anions and cations. I am unable to understand it.
so nice... thx... perfect vids...
Thank You!!!
Why don't you change 3 -2x to 3, as every other video has shown that the change in concentration is small enough to be insignificant? Is that just not done for solubility regarding complex ion formation?
I was stuck on this for a bit too, but I think I figured it out. When we combine the reactions to create a new reaction we got K = 2.9*10^-3. Since K is not a small number (compared to something like 1.8*10^-10) we have to consider x being significant. This was the explanation I was able to come up with, but please if I am wrong correct me.
Thanks man
Hats off man
Thank u so much. LOVE from Bangladesh
Tysm
Thanks a lot for this
Thank you
🙏thnx
For an exam like the MCAT without a calculator, when you square root the exponent of -3, does it come out as -3/2¿
Nice sir
muy bein
For part b, why did you write the reaction with ag+ and not cl-?
+Yusuf Siddiqui cause only ag+ can react with nh3 .. it's an lewis acid , so they will make a coordinate bond
Why is K multiplied and not added ( like Kf+Ksp )
Why is there a coefficient in front of the NH3 in the equation? How do we know it's 2 (NH3)?
naturallysimi He balanced the equation
@@ameyvenkat1488 How do you know that it has a subscript in order for it to be balanced??
💕💕
What happened with cl-
Whenever it's this guy's videos, they are sooooo quiet! I have my volume all the way up and I basically need headphones to hear over my AC running
Why did we multiply ksp with kf instead of adding?
you just have to learn it :) it's like that, i know it's not an explanation but i don't know either i can only tell you that you just got to learn it :)
Snam Snae equilibrium constants are multiplied not added
Write down the formula for the K of the net reaction. Next to it write down the formulas for the K of the other two reactions. Should be obvious now
What is the formula of Kf?
Conc. Of product devided by product of conc. Of reactnts to their stochiometric coefficient
the sound is like shit hope u raise it one day
During the MCAT, we won't have a calculator. Y'all ought to use realistic example and math tricks to solve without one.
Studying for jee
i’m fucked
Very clear explanation but the audio seems to be very low.
