Constants Periodic TableHydrates are solid compounds that contain watermolecules. When hydrates are heated, the watermolecules evaporate, producing the anhydrousform of the compound. The formula of a hydratemay be written in two different ways. For example,aluminum chloride hexahydrate can be written as(Al(H2O)6]Cl3 or as AlCls 6H2O. The firstformula more accurately shows the bondingarrangement, whereas the second formula makes iteasier to see that the anhydrous form of thecompound is aluminum chloride.Part BIF 12.0 g of MgSO4 - 7H2O is thoroughly heated, what mass of anhydrous magnesium sulfate will remain?Express your answer to three significant figures and include the appropriate units.> View Available Hint(s)IA?ValueUnitsSubmitPrevious AnswersX Incorrect; Try Again; 28 attempts remaining3:18

Think of forming an ionic compound as three steps (this is a simplification, as with all models): (I) removing an electron from the metal; (2) adding an electron to the nonmetal; and (3) allowing the metal cation and nonmetal anion to come together. a. What is the sign of the energy change for each of these three processes? b. In general, what is the sign of the sum of the first two processes? Use examples to support your answer. c. What must be the sign of the sum of the three process d. Given your answer to part c, why do ionic bonds occur? e. Given your above explanations, why is NaCl stable but not Na2Cl? NaCl2? What about MgO compared to MgO2? Mg2O?
Define the term lattice energy. Why, energetically, do ionic compounds form? Fig. 3-8 illustrates the energy changes involved in the formation of MgO(s) and NaF(s).
