Just a few questions for Mr. Paige...


1. On the sheet titled "symbols, formulae, and charges of
some common ions," why does it say HPO(sub3)(sup3-)? Isn't it supposed to be PO(sub3)(sup3-)? Also, is HPO(sub4)(sup2-) just "hydrogen phosphate" or "monohydrogen phosphate"?

2. Also, what is the difference between dioxide and peroxide? Would H(sub2)O(sub2) be "dihydrogen dioxide" or "dihydrogen peroxide" or "hydrogen peroxide"?

3. Also, is acetic acid HC(sub2)H(sub3)O(sub2) or H(sub4)C(sub2)O(sub2)?

4. Also, is there such thing as "ammonium aluminum sulfate"? I can't figure out the formula for that one...

5. Also, if the problem does not specify an aqueous solution should we assume and write it as an acid or just "hydrogen [anion]"?

6. Also, does mercury (I) always have to be Hg(sub2)? Does that mean that mercury (I) will always appear as Hg(sub2) in any formula?

7. Is CuNH(sub4)PO(sub4) "cupric ammonium phosphate"?

Sorry to bother you... just had a few questions that I thought you might be able to resolve before I turn this in on Monday to Mr. Groce.
