Chemistry Solubility Questions:

breathe oxygen which is dissolved in water. a. Using what criteria would you assume that oxygen does not dissolve well in water? b. Name and describe the nature of the attraction between the oxygen molecules and the water molecules that allow some oxygen molecules to dissolve in water. Describe how ionic compounds dissolve in water. Use sodium chloride as an example. Give a detailed description including the name of the attraction. Suggest why some ionic compounds are not soluble. Sulfur is a solid at room temperature but chlorine is a gas. Explain. (3) 3. Hydrogen sulfide has a boiling point of 60C and ammonia has a boiling point of 33C. Account for these difference. 9. Graphene is a single sheet of graphite. By placing tape on a sample of graphite and ripping it off, you can get a layer of graphene. A student argues that this contradicts the idea that graphite is held together by the strongest attraction, network covalent bonding. Through a discussion of the bonding in graphite, help the student understand what is taking place
