Chemistry question
Why does something acid based disolve something carbon based? What makes you think this is a solubility rule? I can think of hundreds of exceptions. Carbon disulfide in aqueous solutions of acids, carbon tetrachloride in HCl, etc.

Great! I understand now that C0=f(a) c1=f'(a) c2=f"(a)/2 Now, If I am to find the parabolization of the equation x^2-x at x=2, then c0=x^2-x=2^2-2=2 c1=2x-1=2(2)-1=3 c2=2/2=1 So, the equation (taken from c0+c1(x-a)+c2(x-a)^2) is >> 2+3(x-2)+1(x-2)^2?? Is this co...
