Homework Help: Chemistry

Find the value of delta H net for the following equation:

SnBr2(s) + TiCl4(l) -> TiBr2(s) + SnCl4(l)

I know that I already posted this once but I am still lost on what to do.

I know that TiCl4=-804.2 and SnCl4=-511.3 but I thought that the values for SnBr2 is 0 as well as for TiBr2.

SnBr2 is not zero.
TiBr2 is not zero.
I don't know what they are but they aren't zero. The only DHf values that are zero are elements which appear in an equation in their normal state. O2(g), H2(g), etc.

How should I go about solving this problem? Am I missing information?
