This question has multiple parts. Work all the parts to get the most points. Calculate AH for the reaction 2K() + 2H,О(1)- 2КОН(ад) + На (9) Substance and State AH (kJ/mol) K(s) KOH(aq) H2(g) H2O(1) -481 -286 ΔΗ -390 kJ bA 5.50-g chunk of potassium is dropped into 1.00 kg water at 24.6°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!) Temperature = Submit
