Im preparing for a CLEP test in precalculus. As part of my prep, I need to review identifying domains of functions. I have a question about writing domains in standard notation. I was hoping someone could explain a bit the style.
For an example:
x-2 / x^2 -2x -35
As a rational...
This problem seems simple enough, yet my professor says my answer is incorrect. Here is the problem.
1 ml of a 0.10 M solution of HCL is added to 21 ml of distilled water. What is the final concentration of the solution (M)?
Im going to use the equation
C1*V1=C2*V2
Where C1 is the...
The pKa for the dissociation of H3PO4 is 2.15. What is the concentration of H2PO4-1 (in M) at pH 3.21 if the original concentration of the phosphate was 2.37 M?
My Attempt:
Key Information:
pH final: 3.21
Initial Molarity of phosphate: 2.37 M
pKa: 2.15
I started with the first...
