Question

When 2 moles of calcium chloride are dropped into 1 liter of water at room temperature, all of the calcium chloride spontaneously dissolves and the solution gets very warm. What are the signs of ΔH, ΔS, and ΔG and the value of K for the dissolving? Circle the appropriate answer for each. (8 points – 2 each)
