Unformatted text preview: How many electrons would a chloride ion have? 8) Which of the following atomic numbers describes the element that is the least reactive? (circle one) 1 8 12 16 18 9) If solution A has 5000 times as many hydrogen ions as solution B, by approximately how many pH units do they differ? 10) Explain the hydrophobic effect, i.e. the effect that prevents oil from mixing with water (a few sentences and maybe a diagram): 11) Circle the functional groups (that were discussed in class) contained on the molecule drawn above and give their names. Label, on the regions circled in red above, what is circled and describe what atoms it is bonded to. 12) Draw two amino acids. Label their functional groups. Show how they are joined together to form a dipeptide....
