Consider the following reaction:
2K(s) + 2H2O(l) -> 2KOH(aq) + H2(g)
delta H = -390 kJ
A 5.00 g chunk of potassium is dropped into 1.00 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
The final answer should be around 29.92 C. Please explain how to do it.
