1) Determine the value of delta H net for the following equation:

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

I am not sure how to solve this.

delta Hf = dHf
dHrxn = (n*dHf products) - (n*dHf reactants)

for TiCl4 i got -804.2 and for SnCl4 I got -511.3 and then i subtracted them to get -292.9 but I dont think this is right.

You didn't use ALL of the products nor ALL of the reactants.
