Dissolving 3.0 g of cacl2 in 150.0 g of water in a calorimeter (figure 5.12) at causes the temperature to rise to 25.8 c. what is the approximate amount of heat involved in the dissolution, assuming the heat capacity of the resulting solution is 4.18 j/gc? is the reaction exothermic or endothermic?

How does the value of the equilibrium constant show that a reaction reaches equilibrium very quickly? (a) the equilibrium constant is large. (b) the equilibrium constant is small. (c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
