My Question is the first picture. Others have tried to answer but I don't follow there use of variables/ algebra. I want to know how my instructor went from :
--> 2 [HA] = [A-] to 66.6% both algebraically and scientifically
Please don't respond to this question if you are unwilling to explain !!!!!! STOP using letters to justify your algebra! I don't understand how the variables are equal or even equilavent. Please continue this question step-by -step without letters.
![5.1 = 48 + los e 1083 = 2 = 14 J = 7 - 66.6 %. Ionized A-] ( - 11/27 (HA) 1 2 [HA] - [A-](http://img.homeworklib.com/questions/327abcd0-dc6e-11eb-a7c5-afca4cfdccd6.png?x-oss-process=image/resize,w_560)
Do NOT use short hand! this is unaccepable:
Homework Answers
We assume that only 2 forms of acid exist at equilibrium, that is HA & A-.
Thus, there total concentration becomes 100. Hope,this helps in clearing your doubt. feel free to ask for any further queries regarding the solution.

I think I have 1a. but I don't know the other parts.
In class, we showed for the classical harmonic oscillator that: E_ = 1/2 kA^2, where k is spring force constant and A is the amplitude of oscillation. We found that the harmonic oscillator had angular frequency expressed as: omega = Squareroot k/m. We also discussed in class for the classical harmonic oscillator: E_ = E_k +V with E_k = 1/2 mv^2 and V = 1/2 kx^2 a.) Use...
