17. (10 pts) Solid potassium metal reacts with liquid water to produce aqueous potassium hydroxide and hydrogen gas as shown by the BALANCED chemical equation below. When a 3.50 g piece of K(s) is added to 150. g of water in an insulated container, the temperature of the liquid INCREASES from 25.0 °C to 65.8 °C. Calculate the enthalpy of reaction (4FH) for the reaction in the forward direction. Water has a heat capacity (Cp) of 4.18 J/(8 °C). Assume...
