The heat of solution of ammonium chloride is 15.2 kJ/mol. If a 6.134 g sample of NH4Cl is added to 65.0 mL of water in a calorimeter at 24.5°C, what is the minimum temperature reached by the solution? (The specific heat of water = 4.18 J/g·°C; the heat capacity of the calorimeter = 365. J/°C.) 27.1°C 18.6°C 19.7°C 21.9°C 30.4°C The bond enthalpy of the Br–Cl bond is equal to ΔH° for the reactionBrCl(g) → Br(g) + Cl(g).Use the following data to find the bond enthalpy of the Br–Cl bond.Br2(l) → Br2(g) ΔH° = 30.91 kJ/mol Br2(g) → 2Br(g) ΔH° = 192.9 kJ/mol Cl2(g) → 2Cl(g) ΔH° = 243.4 kJ/mol Br2(l) + Cl2(g) → 2BrCl(g) ΔH° = 29.2 kJ/mol
