i'll give you a hint seeing as it's your homework, all of the answers are to do with hydrogen bonds and hint for number 5 - if water had a lower vaporization it would be gas at room temp - does that sound good? hint for 6 OH is alkali H+ is acid, water is neutral so what do you think the proportion would be, ooo and hint for number 2 have you done any washing up lately ever seen anything float ontop (cough oil maybe cough) ok yeh enough hints everything else will come when you grasp the concept of hydrogen bonding. sorry to not directly give the answers but trust me when you start to make the connections yourself they'll last a lot longer.

1) Because it dissolves so many things
2) Oil-like hydrocarbons and inorganicsalts whose ions are unavailable for solvation
3) It hs such a high specific heat because it is associated: The slightly (+) H's of one molecule are attracted to the slightly (-) O's of another.
4) Same reason
5) Sweating keeps you cool; water evaporating from a dog's tongue keeps him cool.
6)a)b) [H+] = [OH-] = 1 x 10^-7
