The Ksp of calcium carbonate is 4.5E-9. What si the concentration of calcium carbonate in equilibirum in water? -do i make an ICE table and please explain Ksp.

what is the solubility of barium sulfate in a solution containing 0.050 M sodium selfate? The Ksp value for barium sulfate is 1.1E-10. An insoluble salt with formula MX3 has a solubility product constant written in terms of solubility,s, in the form a) Ks...

I have many questions. I have a test tuesday and need to get these problems done and understand them today because i am currently studying. I am in college and my professor has not emailed me back regarding solutions for the review problems she posted. Is...

How to determine which of the compounds will have the lowest boiling point vs the highest boiling point?

I want to understand this concept more than anything so advice as well as hints to solve this problem are greatly appreciated. 26. Two fixed charges, -4.0E-6 C and -5.0E-6 C, are separated by a certain distance. a) is the net electric field at a location...

for #1:i still don't get it because the answer is c) [H+]=(Ka[HA]).

another question: Which of the following solutions will have the largest temperature range for the liquid state? 1) 1M C3H8? (ethanol) 2)1M CH3COOH (acetic acid) 3) 1M KBr(Potassium Bromide) 4) 1M MgBr2 (Magnesium Bromide) I answered b, since it was the l...

the largest I value would be MgBr2 because it has 3 ions, KBr has 2, and the other 2 are - to 1 because they do not split, correct? What about my first question? About determining BP highest or lowest. Does the same principle apply?

ok thank you. It is ethanol, not propane o that would make sense.

i do not know if this is right but this is how i would do it. M1V 1=M2V2. (0.00307 M) X (150ml)= (M2) X (30 ml) and then you solve to get m2
