Calculate ΔH° for the reaction -> 2 K(s) + 2 H2O(l) 2 KOH(aq) + H2(g) A 4.85-g chunk of potassium is dropped into 1.06 kg water at 24.0°C. What is the final temperature of the water after the preceding reaction occurs? Assume that all the heat is used to raise the temperature of the water. (Never run this reaction. It is very dangerous; it bursts into flame!)
