Tin and Chlorine synthesize Stannous Chloride according to a two step mechanism:
Sn (s) + Cl2 (g) ⇌ SnCl2 (s) + 83.6 kcal
SnCl2 (s) + Cl2 (g) ⇌ SnCl4 (l) + 46.7 kcal
Determine the overall heat of reaction and write the final equation for the reaction.
Show work, please.

Did you make a typo? SnCl4 is stannic chloride.
Sn (s) + Cl2 (g) ⇌ SnCl2 (s) + 83.6 kcal
SnCl2 (s) + Cl2 (g) ⇌ SnCl4 (l) + 46.7 kcal
Add equation 1 to equation 2 and add the heat of formation from each step.
