The reason that metal oxideshow an acidic nature in a high oxidation state, while show a basic nature in a low oxidation state, is to be explained. Concept Introduction: Elements combine with oxygen atom(s) to form oxides. They, then, react with water toeither produce an acid or a base. In their lowest oxidation number, all alkali and alkaline earth metal oxides are basic in nature. Some metal oxides, in ahigh oxidation state, show acidic behavior. All nonmetal oxides are acidic in nature in their highest oxidation state. They are considerably neutral in their low oxidation state. In any case, nonmetal oxides do not show basic nature. Metallic oxides show acidic as well as basic natures, according to the reaction conditions. These are called amphoteric oxides.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.

19. (3 pts) in Chapter 7 we will see a reaction of halocyclohexanes that requires that the halogen occupy an axial position with this in mind, would you expect cis-1-bromo-3-methylcyclohexane or trans-1-bromo-3-methylcyclohexane to be more reactive in this reaction? Briefly explain your choice using structures to support your answer. Mere-eries-cecleone) The tran-i-browse-3-methylcyclohexione
