7. For each of the bonds/interactions listed in question 6, determine if the interaction is intermolecular or intramolecular, which bonds are strong and weak and provide an example of each. 8. Explain the difference between polar and nonpolar covalent bonds. Give an example of each. 9. Draw a molecule of water and show the arrangement of electrons in the three atoms. Label a hydrogen bond, a covalent bond, a partially negative atom and a partially positive atom. 10. Describe adhesion, cohesion and surface tension. How does the structure of a water molecule give water these properties?

Name: ___________________________________________________ Period: _____ Date: ________ 11. Why do coastal regions tend to have climates with moderate temperatures and lower annual variation in temperature than do inland areas at the same latitude? 12. Why does ice float? 13. Why does spring and fall cause the water to turnover in a lake? Why is this turnover important to the ecosystem of the lake? 14. In an oil spill, why does the oil slick spread out over the surface of the water? Explain the chemical interactions that cause this phenomenon. 15. Carbon dioxide and water react to form carbonic acid: CO 2 (g) + H 2 O (l) H 2 CO 3 (aq) In aqueous solution, carbonic acid immediately dissociates to form a proton and the bicarbonate ion: H 2 CO 3 (aq) H + (aq) + HCO 3 - (aq) Does this reaction raise or lower the pH of the solution? Does the bicarbonate ion act as an acid or a base? If an underwater volcano bubbled additional CO 2 into the ocean, would the reactions be driven to the left or the right? How would this affect the pH of the ocean? 16. Draw an atom of carbon including its electrons in electron shells. How does carbon’s structure lend to its versatility? 17. Describe the three types of isomers and provide an example of each. 18. Make a chart of the 6 major functional groups. Include the name of the functional group, its structure, the name of compounds, and properties of those compounds. 19. Distinguish between a dehydration reaction and hydrolysis. If a polysaccharide’s molecular formula is C 48 H 82 O 41 , how many monosaccharides were combined to make this polysaccharide? How many molecules of water were removed? 20. What are the six main elements found in macromolecules? Name the elements found in each of the four macromolecules.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
