Quadratic Equation ICE Table Equilibrium Calculations

[@princebattu7554]

Who's here watching to prepare for the test tomorrow?

[@NateManG]

Got a nice 40% final tmr and i still dont know ice tables xD

[@datguydatguy1129]

nah i'm here for the test in two days

[@Moleqlar]

So, did you pass your test?

[@princebattu7554]

@@Moleqlar yeah but I flunked my cross curricular :(

[@EciOwnsYou]

Awesome job at explaining the steps. Thanks a ton!

[@Moleqlar]

Esmir M. Thanks! Glad it helped!

[@JPX28]

Wow, explained perfectly! Thank you so much! ❤️

[@JkJk-rt3zj]

thank you so much, all is clear now. still a useful video after 7 years!

[@maestromalave1400]

Thank You For your expert explanation and great narration have a great day !

[@Aaa-cf4dx]

dont wanna sound dumb but how did you got (6.00 - 5.00 + x^​2) at 7:22 ?

[@Moleqlar]

By "foiling" (2-x)(3-x). 2*3 = 6. 2*-x [in second bracket] = -2x 3*-x [in first bracket] = -3x -2x + (-3x) = -5x -x * -x = x^2 [no operator means +] The put it together. 6 -5x +x^2

[@Aaa-cf4dx]

Moleqlar okay thanks so much

[@Jess-gr8kv]

@@Aaa-cf4dx im with you, where did the 5 come from? i get that 2x3 is 6, then -X x 3 is -3x...not 5

[@Moleqlar]

@@Jess-gr8kv 2*-x and -x*3 = -2x - 3x = -5x (original writer omitted the x)

[@TheKittahMuncha]

I'm just here trying to figure out how to get from the ice table set up to rearranging the equation for the quadratic. I am lost at how you got 6.00-5.00x+x^2 in the denominator. Do you have a video explaining step by step to get to the quadratic equation?? I get everything else besides that >.

[@slopcrusher3482]

You have to foil, or multiply the first things, then outside things, then inside things, then the last things. So if you had (1.00-x)(2.50+x) 1. First, so 1.00 x 2.50 = 2.50. You multiple the first things. 2. Outside, so 1.00 times x = 1.00x you multiple the things to the outside 3. Inside, so -x times 2.50 = -2.50x you multiple the things inside 4. Last, so -x times +x = -x^2 you multiple the last terms together The equation would then look like… -x^2+1.00x-2.50x+2.50 which adding like terms would give -x^2-1.50x+2.50

hey if we try to do using degree of dissociation won't we take 2 - 2 alpha and 3 - 3 alpha ?

[@charlottecore]

thank you so much honestly i understand it so well now 😭🙏

Love your work mate

[@Moleqlar]

Thanks Heath. Still so much to cover so I'll be coming our for more videos shortly

the challenge i had has been sorted,ICE method of finding missing concentrations,thank you so much. moleqlar

[@Moleqlar]

My pleasure! Good luck.

[@jond3929]

What do you do when both results from the quadratic equation are negative?

[@Moleqlar]

There may be something gone awry when doing the math using the quadratic equation. I always suggest doing everything within the square root first, and then once you have that value, perform your two root calculations: -b - ANS/2a and -b + ANS/2a

[@_jazzhandzz]

thanks! such a great explanation (:

[@arefhamaoui9962]

great video.

[@إبراهيمخليل-ي4ه]

Thank you so much❤😍😍💕

[@Jesus.saved.me2000]

Thank you!! Helped tremendously

[@kpop-universe483]

I got a problem in chosing value of x because both value smaller than initial concentration

[@hunegnawzewude2110]

There is a mistake when you move 4x^2 to other side.It would be negative so they can add and become -29x^2

[@omar1x.]

25x^2 is positive and switching 4x^2 to the other side would become negative therefore you have to subtract

[@Jwilb]

You're amazing

[@bananasaging9234]

Thank you for this!!

[@JohnLivanos-y7l]

how was the square root of 302.5 = 55

[@yellowroo]

my calculator doesn't like it when I input a negative value for b in the square root. I get MATH ERROR. but from what questions I've done just always keeping it as a positive regardless gets the answer still

[@Moleqlar]

It's all about the order of operation. Try using brackets or if your calculator has a specific quadratic function, try using that.

[@yellowroo]

@@Moleqlar No worries, hope I don't need any chemistry units in future

[@josie.a.p]

My chem teacher told us to use this but never taught us how because "she's not a math teacher"

[@Moleqlar]

Maybe your teacher's strengths lie in organic chem where there is less math, or possibly in another science. Either way, I'm happy that I was able to help :)

[@josie.a.p]

@@Moleqlar shes also a math teacher but I think she was saying it because she's not OUR math teacher at the moment. Ahh so annoying lol

[@Moleqlar]

@@josie.a.p That makes absolutely no sense on her part - if she has the skills to explain, why withhold them? Sorry that you're going through this. Just use my lessons to help you and your classmates get through.

[@ElykKetrab]

Since these are gasses, why didnt you use Partial Pressure instead of Molarity?

[@strongbodystrongmiind]

Kyle Bartek you would get the same answers

[@DazedDanyy]

It asked for Concentration of each gas. Not the partial pressure of each gas.
