Importance for Human Physiology
Thankyou so much saved my life you explain it so well. I got a chem benchmark mark so i figured that i should figure it out rather than guess from what me teacher taught
AAAAAAAAKKKWEEEEEEEEEUUUUUSSSSS solution bad pronunciation.
thank you so much for uploading this video it helped me alot!!!
Shouldn't the net ionic be Pbl(subscript 2) not 2Pbl(subscript 2). Not sure where the 2 coefficient comes from. Thanks! 🙂
AWESOME!!! Perfect MCAT Review!!! 🙂
Very helpful video. I have a much better grasp of this now.
Thank you so much. My chemistry professor had screwed me up and made it more complicated than it was supposed to be. You made it much simpler so thank you!
great teacher !!! thanks a lot keep up the good work!!!! Thank YOU VERY MUCH!
Forgot how to do net ionicThanks~ Swept my worries right into the trash
should end with Pb2+ + 2I- = PbI2
So helpful, thank you so much!!😁
why do you get 2 PbI2 rather than just PbI2?
Sooo… I think I love you.
On your net ionic equation, where you have Pb + 2I –> 2PbI2 shouldn't it say (s) after the product instead of (aq) since we were talking about a precipitate?
Thank you this video helped me a lot!
Very helpful! Thank you!!
You are a God among teachers! I love you!
This is very helpful!!
Helpful and simple
As a fellow chemistry teacher, I appreciate using your videos as additional resources. They are great! However, there are two errors in this video. The net ionic equation should show only 1 mole of lead II iodide (should not have a coefficient of 2 in the equation). Also, the descriptor for the ppt is incorrect and should be listed as (s) and not (aq). Love your videos 🙂
how do you know when it is aq or solid. In my class we used some kind of table to predict it.
Is it just me or is precipitate spelled wrong?
Thank you so much for making these videos! I probably would have failed Chem 124 and Cell and Molecular Biology if it wasn't for all the helpful videos you've produced. 🙂
Thank you! Really wish you taught at my college… these professors cannot teach.
seriously ur one of my favorite people, thanks for being such an awesome teacher! people like me really appreciate someone walking you through it 🙂
Wooow. I get it now! Thank you so much!
Thank you! This helped a lot! I was confused by this in class, but watching your video really helped!
I will forever be grateful for your videos.
Why didn't you write lead nitrate as "lead (II) nitrate"? This was really helpful, don't get me wrong, but I just got confused there and I went searching for nomenclature videos to help me understand how to write formulas.
Great video as always! Pretty sure the pbI2 is solid and not aqueous though at the end there in the NIE though!
i love this channel! you sir are amazing!
I love you bozeman
At 6:30 how would you know that the PbI2 is a precipitate
hi, first and for most, thank you for all your videos, they are very helpful. i have a question. how do we know on 5:40 that PBI2 is a solid?
Yes i can finally say I truly understand without hesitating
Thanks so much
Thank you so much! I wasn't understanding this concept in class, and found this video at home. After watching it, I now understand the concept I was not understanding without hiring a tutor and saving my grade. Again, thanks for the well developed and helpful video!
I don't understand how the lead iodine became aqueous in the net ionic equation, also how is that equation balanced? To me it's saying that there's 4 iodine in the product compared to 2 in the reactant, along with 2 lead compared to 2
you as well as tyler dewitt have saved me from chemistry
Very helpful! Thank you 🙂
Hello Sir, what type of Ionic reaction would this be:Na2CO3 + 2H[+] —> 2Na[+] + CO2 + H2O
I'm not sure if I balanced that right.
Also, what is the state (l, s, g, aq) of each compound? Na2CO3 (?) + 2H[+] (?) —> 2Na[+] (?) + CO2 (?) + H2O (?)
You always help clarify things for me!! Thank you!
thaaaaaaaannnnnnnkk you very much
I think there is a mistake at the final answer of the ionic equation.
Does anyone else have chemistry test tomorrow? :))
precipitate not precicipate
does anyone know when he does ionic equation he just keeps PbI2 (do not break into Pb^+2 and I2 ), does anyone know why? please Help me out TT^TT
it was very very helpful !
HOW DO YOU KNOW WHERE THE SUBSCRIPTS GO IN THE EQUATION I NEED HELP
Thank you!! You've helped me a lot
Nyc one ma guy……you ve just made an A for me.keep it high.
that was very helpful. Thank you!!!
How do you magically get 2PbI2 from 1Pb and 2I? Also, how do remove spectator ions with different coefficients?
You didn't even show how to get the molecular equation. You can't just write it down and not explain it.
I am pretty sure there are two mistakes for the net ionic equation:
1. Pb2+ + 2I- –> 2PbI2 does not make sense, it is not balance. Should it be:
Pb2+ + 2I- –> PbI2
2. Since PbI2 is a precipitate, it should be PbI2(s). Every equation except for the net ionic equation write that correctly, but the net ionic equation writes it as PbI2(aq).
I am not trying to be a jerk about this, but I just wanted to let you know. If I am mistaken, could you please explain why? Thank you.
Thank you so much! I am in Chem 111 and this video helped out a lot!!!
omg thank you
at 7:54, the 2PbI2 should be solid, not aqueous, right?
thank you !!!
i always end up watching this guy for one reason or another…strangely, over a wide variety of subjects…how does he know so much useful stuff? Hmm…I will stay in school…
omg this saved me for my midterm tomorrow!!!
Anderson you beautiful son of a bitch. Thank you so much!
i want to die
I actually understand. thank you. now I a chance of actually passing my test Tmr.
Thank you so much for the life-saving video. But I am still uncertain how you know that PbI2 is a solid, not KNO3. By that, I mean how do you know that KNO3 are spectators ions to cancel out?
Thank you so much! I have a chemistry test tomorrow and I didn't understand anything about ionic equations, but after watching this video everything is much clearer. Thank you!
When you have half a million subs but you can't buy a decent microphone
why do i have to look at your stupid face to learn this video?
This is literally the greatest and most blatant video ever
It was amazing
Thank you!!! That's very help full
How do you know if the ions are going to break apart?
8:06 there should be Pb2+(aq) + 2I-(aq) —> PbI2(s). Two mistakes, I hope this helpful.
this is helpful but I'm still going to fail
great video to watch when you get high and forget about a quiz tomorrow 🙂
did you make a mistake at 8:06 with 2PbI_2….shouldn't it just be 2PbI
at 8:02 the Pbl went front being a solid to being an aq. That was just a mistake, right?
I wish I saw this guy when I was in chemistry
Bperor pokor tu hikaiso kela
GOD I hate this class. why were ionic equation evn put into general chemistry. This stuff should not be required
For your Net Ionic Equation, shouldn't you Lead Iodide say (s) for solid instead of (aq) because it's the precipitate? Also so do you have to balance your reaction in the molecular equation and then again in the net ionic equation?
Edit: Forget that last question, in the net ionic equation, the 2 next to the Lead Iodide is just a typo right? (It's already balanced without it).
this is very helpful, thank you very much
trash video bro didnt learn anything
how the fuck are you supposed to do this without any helping material for Ammonium phosphate and zinc nitrate. im really fucking stuck
I have a quiz in 30 minutes and I just learned this, thanks my guy
8:00 did he mean solid for 2Pbl2*(aq)*?
Thank u so much 😊
