The difference in electronegativity between H and O in water allows for water to experience , which is what causes strong . a. hydrogen bonding; surface tension
b. hydrogen bonding; conductivity
c. adhesion; hydrogen bonding

it's c. elements are placed in rows based on how may valencies electrons have.

your answer would be “dry”

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
