Question

According to question 3 from The Additivity of Heats (Hess's Law) Worksheet what is the change in enthalpy (kJ) for the following reaction?  Do not type units into your answer.

 

SiO2(s) + 4HF(g) ⟶ SiF4(g) + 2H2O(l)     Δ?=? 

3. Given the following information, calculate AHxn for SiO{s) + 4HF(g) → SiF«(g) + 2H2O(1)
1. AHt of SiO2(s) = -910.9 kJ/mol
2. AH: of HF(g) = -271.1 kJ/mol
3. AH: of SIF4(g) = -1614.9 kJ/mol
4. AH: of H2O(1) = -285.8 kJ/mol
