This is a question I am presently doing right now which I found in my homework. I am quite sure that in (a) I have to use the Hasselbach equation though I am not sure how to work it out. If anyone knows any of the answers, and how you got to them, please feel free to share. Any help is greatly appreciated :)
CH3COO- (aq) + H2O (l) <==> CH3COOH (aq) + OH- (aq)
A 0.01mol dm^-3 solution has a pH of 8.87
a. Calculate [H+] and [OH-] in the solution
b. Find [CH3COOH] in the solution.
c. Calculate the acid dissociation constant of CH3COOH.
Thanks! :)

Why is the shape of the molecule square planar in dsp2 hybridisation? Shouldn't it be tetrahedral like sp3 hybridisation ( because 4 hybrid orbitals repel each other acquiring a tetrahedral shape)? Which d orbital participates in this hybridisation and why?

Does aluminium interact with palmitate in solution?
For context I am conducting an experiment on isolated mitochondria. Measuring the effects of aluminium and palmitate on respiration. I am seeing something but I am not sure if the two molecules are simply binding together and precipitating out into solution or if they are actually affecting part of the ETC.

Copper is sometimes coated on the bottom surface of cooking pans. Copper has a specific heat of 0.385 . A 25.3 sample of copper heated to 86.0 is dropped into water at an initial temperature of 14.5. If the final temperature reached by the copper-water mixture is 36.0, how many grams of water are present?

If the caffeine concentration in a particular brand of soda is 3.23 mg/oz, drinking how many cans of soda would be lethal? Assume 10.0 grams of caffeine is a lethal dose, and there are 12 oz in a can.
