Compound Δ Hrxn (kJ/mol) NH4NO3 + 25.7 KCl + 17.2 NaOH -44.5 KOH -57.6 You are given 6.9 grams of an unknown salt. You dissolve it in 56.5 mL of water. As the salt dissolves, the temperature of the solution changes from an initial temperature of 28.9°C to a final temperature of 22.9°C. Based on the chart of ΔH values and the temperature change, you can determine which salt you have. What is the temperature change? Δ T = o C...
