1. The standard enthalpies of formation of HCl(g) and HBr(g) are -92.0 kJ/mol and -36.4 kJ/mol respectively. Write the formation equations for both HCl and HBr. These are your known equations.

Then, using this information and Hess's Law, calculate ΔH for the production of 175g of HCl based on the following reaction: Cl2 (g) + 2 HBr(g) → 2 HCl (g) + Br2 (g)

(make sure solution Is clear)

2. Often when an injury occurs at a sporting event, the injury is treated with an ice pack. The chemical reaction inside an ice pack usually involves water and a packet of ammonium chloride. The cold pack is activated by breaking the barrier separating the water and ammonium chloride, allowing them to mix. The reactions is: NH4Cl(s) + H2O(l) → NH4+ (aq) + Cl-(aq)

The molar enthalpy of solution for ammonium chloride is +14.8 kJ/mol. What is the final temperature of the ice pack that is observed when 20.0g of ammonium chloride is added to 125 mL of water at 20.0°C ?
