1. The problem statement, all variables and given/known data Write the charge balance for a solution containing H(+), OH(-), Ca^(2+). HCO3(-). CO3^(2-) , Ca(HCO3)+, Ca(OH)+, K+, and CIO4(-). 2. Relevant equations Also, I am having a trouble understanding the concepts of mass balance and charge balance. 3. The attempt at a solution The only thing I know to do is put the positive charges on one side and the negatives on the other, and then change the coefficients.

Calculate the pH of 5.0 x 10^-8 M HCLO4. What fraction of the total H+ in this solution is derived from dissociation of water?

I was contemplating majoring in chemistry when I go back to university. I don't want to do this physics (not that i don't like physics nor is it that i can't - just not interested in taking the classes). Thus, I would do a Bachelors of Arts instead of science to avoid the physics. I was thinking pharmacy school after this, or stopping with Bachelors. How does the difficulty change as one progresses through the major? General Chemistry (not a big fan; made good grade without studying much; easy at cc) Organic Chemistry (took, dropped; loved it) Physical Chemistry (not taken) Biochemistry (not taken) Analytical Chemistry (not taken) Inorganic Chemistry (not taken) Other Upper Levels. How does the difficulty change from each? Is physical more like general than organic? If chemistry major is anything like organic chemistry, then chemistry is definitely for me.

I like organic chemistry, and was thinking about majoring in chemistry (BA in chemistry),. Does anyone know how the difficulty changes from organic chemistry to physical chemisry, biochemistry, analytical chemistry, etc... I wasn't a huge fan of general chemistry bud loved organic chemistry.

In my organic chemistry class, the lecture notes and professor does not label any of the reactions as "SN1, SN2, E1 or E2," and nor does the textbook. However, many of the video tutorials online as well as in my prior organic class at another school, we used such classifications. Can anyone explain why this is such?

Generally, in organic chemistry, is it advisable and/or necessary to memorize the catalysts of reactions. For example, H2 reacts with alkenes to produce alkanes in the presence of transition metal catalysts. (commonly: Pt, Pd, Ru, Ni). Do these need to be memorized, and how does this apply to other reactions not just reduction of alkenes.
