What type of chemical bond holds Lit and F together in LiF?
a
lonic Bond
b Metallic Bond
C Covalent Bond
d Molecular Bond

The correct answer is a) lonic Bond

Explanation:

Lithium fluoride (LiF) is a salt, formed by an ionic bond between a metal (Li) compound and a nonmetal (F).

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.
