Thank you for explaining whre the positive and negatives go! it was so hard to find an example where the initial product and one of the initial reactants were given
Everyone is saying this is perfectly explained but he did not explain how he got the -.08 for 4x2-.08=.0004....I see how we got 4x and the .0004 but not the middle number.
How did you get .08x for the denominator ? im so confused on how to do these types of problems & you didn’t go into enough detail on how to actually solve the problem you rather implemented the answers you got onto this paper without fully explaining how to get the values being written down
Explaining where the positive X goes and the negative X depends entirely what you start with. A lot of Equilibrium questions start with ONLY reactants and NO products, which means the concentrations of the REACTANTS can ONLY go down (thus -x), and the products can ONLY go up. KEEP IN MIND THO that the x values might be multiplied by the coefficients. So 2 moles of reactant mean you have to subtract (-2x) in the CHANGE portion of the RICE table. OTHER equilibrium questions have partial quantities of Reactants and products IN THIS CASE because one product is at ZERO, the products MUST GO UP (thus +x or +2x or +3x). HOWEVER in other questions equilibrium is established, and you must figure out what happens to the equilibrium happens when either more product or reactant is added. This might require calculating a TRIAL K value. Trial K values that are SMALLER than the actual Keq value provided MUST shift towards the products(thus +x goes on the product side of the CHANGE line and -x goes on the reactant side. Trial K values that are BIGGER than Keq means the shift goes towards the REACTANT SIDE (which would use +x in the CHANGE LINE and -x for the products on the CHANGE LINE). Understanding this is important.
The reactant are always on the left side, while the products remain on the right side on the chemical reaction. So pretend that you’re reading a book, you go from right to the left to get your product.
You managed to explain a week of classes in 8 minutes THANK YOU
MY CHEM TEACHER IS USELESS I S2G
A week. My teacher 'taught' us in 30mim
7mins and 53 secs actually
You're so clear with how you explain things and you don't skip any small details, thank you SO MUCH! You should make more videos :)
I love you
you showed me in 6 minutes what a website wasn't able to show me in 6 hours
Only ICE table video that's actually helped me! Thank you!
Thank you for explaining whre the positive and negatives go! it was so hard to find an example where the initial product and one of the initial reactants were given
THANK YOU SO MUCH for explaining where "+" & "-" go!!!
hey man thank you so much for this video im like 6 years late but for years i havent been able to understand ice tables. You are the best I am saved 💜
Finally thanks to this gentleman I understand ICE Method 😊
This hurt my head to watch, but you explained it so well! Good difficult problem to really put it all into perspective
Bro cooked 2 vids and dipped we need you come back. It takes so long to find someone who explains in full detail in a short amount of time.
thank you so much for this! i have a test tmr on ice tables and this really made things so much more clearer
the quadratic formula is -b±√(b^2 )-4ac)/2a
That’s awesome thank so much. I was so confused in class, this helps tremendously.
U EXPLAIN BETTER THAN MY CHEMISTRY TEACHER!
how did you get the -.436^2?
Subtracted 1x^2 from the right side and the left. .564-1= -.436
did u ever find out lol
he subtracted .564 by 1
You are my hero! Thank you so much!!!
Isnt it crazy how complicated professors make simple things?
"We keep mathing it out" is my new favorite phrase. Major thank you for this!
How did you turn the .564 into -.436 from switching the x2 to the other side?
1 is the coefficient of x^2 so he had subtracted 1-0.564
Thank you for this video! You made my life a lot easier XD. For your first video this was really intuitive.
THANK YOU SO MUCH! the best video I've seen
this was amazing I've been so confused on the signs for x, thank you so much!!!!!!!!
My professor made ICE tables sound like rocket science, this makes me feel incompetent but thankyou so much
I’m not even kidding, your handwriting looks exactly the same as mine!
Hey! This is very helpful, thanks! I was wondering, if the I is all 0, which side has the negative x's?
i was so confused on one part of the step which was the 4x^2-0.08x+0.0004. it took me 10 minutes to realize where I went wrong
can you explain this to me I have no idea how he did this calculation
How did it happen?
@@nayachryzler4049 foil
Did u understand it ? Pls help @@Aaronobviously
best example anywhere!! thank you SO SO much
Wish I found this in first year lol.
i missed a week of school and this video caught me up to speed you are a godsend
Everyone is saying this is perfectly explained but he did not explain how he got the -.08 for 4x2-.08=.0004....I see how we got 4x and the .0004 but not the middle number.
foil
It's an identity to expand squares of variable numbers. In this question he used a²-2ab+b²
So helpful, I can be confident in getting an A now on my upcoming exam :) thank you!!
chem is so fucking hard, i wanna kill myself everyday
Satnam Singh yeah fuck school
how'd it go?
@@RandomPerson-hd9sb oh, I'm pretty sure I did well, big help with this video probably! It's been so long now ahh. I'm now studying for MCAT lol
@@shelleykim38 how’d the MCAT go?
Thanks dude! I really appreciate this.
The ONLY thing I wished you showed, was step by step the quadratic formula part, but oh well. I get the gist. Thank you!
The world is good because of people like you
You're literally the best human in existence
This deserves more views
How did u get .0004??
its from the squared value of (0.02 - 2x), its was squared because there were 2 mols of BrCl in the given chemical equation
how did u get 1.3 * 10^-3 as the final answer? I don't understand
bro i swear this helped so much I WAS STUCK ON A WUSSTION LIKE GHIS FOR A WHILE
Ty so much for this video!!!
Thank you Justin
You are the clutchest man ever
wh if i dont know math, i litreally didnt get it cuz its not explained from where u got the numbers at the end
He said he got it by the calculator bruv
BLESS YOU BRO
Bruh this helped so much, ty!
YOU ARE AN ANGEL!! THANK YOU SO MUCH!!
Awesome video, 👏🏾👏🏾👏🏾
holy crap this is finally answered my burning question of "why tf is it the change negative?!?!?!?!"
what if the 0s are on the reactants side? would that side then be the +x side?
Yes❤
Mate, how do you have the initial concentration of products as .03 M?
Initially no products exist
Thank you, young wise Professor
How did you get .08x for the denominator ? im so confused on how to do these types of problems & you didn’t go into enough detail on how to actually solve the problem you rather implemented the answers you got onto this paper without fully explaining how to get the values being written down
My teacher literally just said an ICE table would help to solve this but NEVER taught us how to do them
how did it go from .564 to -.436?
He subtracted the x^2 on both sides. (0.564x^2)-1x^2= (-0.436x^2)
Yeah.. shouldn't it be -1.564?
nah nah he did 0.564x^2 - 1x^2. The x^2 gets cancelled and the answer is -0.436
Stefan Ramanayake why do I get -0.681 ?
1-0.564 should give you .436
Thank you this video was really helpful.
Thank you so much!
Thank you for this!
Thank you for this video. Very well explained.
You are amazing ! Thank you
can you not show how to solve the quadratic too???
WOW. thank you so so much!!!
Incredibly helpful!
Wow THANK YOU. This is the best video yet on Ice tables you are awesome!!
why didnt you show us how you put into quad. equation?????
Where did the .08x come from ?
You explained it so well
Thank you!!! So helpful!!
my goat thank you!
thank you so much who was know that you will help me after7 years
so how would you find Kc if you don't have it already given to you? what is the step that I'm missing? any feedback would be appreciated.
So you didn’t have to enter this into the quadratic formula?
This helped so much! thanks!

Thank you!
what if Kc wasn't given?
Thanks man!
I thought the products were on the right side of the rxn and reactants on the left ? Does it matter? Thankyoi and great video helped me a ton
The reactant are always on the left side, while the products remain on the right side on the chemical reaction. So pretend that you’re reading a book, you go from right to the left to get your product.
@@NamrataPrasad1 was his final answer (1.3x10^-3) the value of x?
THANK YOUU!!!
Thank you! I got it :)
Hi! I love this video , but I’m confused where you
Got the .141 from.
Given in the question
Really helped, thanks g
Quick question during the last part the quadratic, you get 2 answers why did you pick that answer and not the other?? 😁
thanks, great tutorial
THANK YOU
Thank you thank you very much sir
great video
hey dude, thanks a lot. it helped :))
i understand it all, but all that bothers me is when do we know which x value to choose?
It’ll tell you in the question which one you’re trying to find
oh yeah i need this my teacher just said hey answer activity 1 wut the hell is ice box ma am
mrs. has left the lobby ol class feels
make more videos!!
Great video omg!!!
The forbidden knowledge!
w
how can we find initial concentrations with the help of kc and equilibrium concentrations?
Dont you have to fill this back into the table nd then into the kc formula to get your answer?????????
if you still watch this comment section, can you do a question with the assumption??
thanks
Thanks it help in clear NEET exam
wow, this is not complicated atall... thanks (From the future)
muito obrigado
