Answer the following question. Show the answer on the screen provided. After uploading your exam, take the picture of your work and upload it to Exam 4 Solutions, Extra Credit, and Partial Credit assignment. Your work must reflect the answer provided here. NO CREDIT will be awarded for the answer without work shown. Use Hess’s law to calculate the enthalpy of reaction for the target reaction 2 Fe(s) + 3 Cl2(g) => 2 FeCl3(s)        from Fe(s) + Cl2(g) => FeCl2(s);                ΔHo  = -341.8 kJ2 FeCl3(s) => 2 FeCl2(s) + Cl2(g);     ΔHo  = +115.4 kJ
