BILD 1 Practice questions for midterm 8/7/08 1) There are ______________ (number) orbitals that comprise the second shell of electrons in an atom. 2) The maximum number of electrons that can occupy a single orbital: 3) Protons (hydrogen ions) in water actually exist as _______________________ ions. 4) Compounds containing only hydrogen and carbon as known as ________________________. 5) Draw the amino functional group. What properties does this functional group have? 6) Give the generic name for the chemical reaction used for synthesizing polymers in a cell. (one word) Give the generic name for the reaction that breaks down polymers. (one word) What molecule do these 2 processes have in common? 7) Chlorine has an atomic number of 17 and a mass number of 35.

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....
