Question

The entropy of a substance increases as we change it from solid to liquid to gas, as we increase the motion and configurations possible (and go from a highly ordered structure to one lacking any structure). With this comes the expectation that dissolving a solid (changing state from solid to aqueous) will increase the entropy of the system. Using Appendix II from your textbook, calculate the entropy for the dissolution of MgCl2, make sure to include the chemical equation you are using with states of matter. (5 points) Did your calculated entropy surprise you? Why or why not? If it did surprise you propose a hypothesis for why it happens
