The Trojans cut down all the trees on the surrounding hills….
Questions
The Trоjаns cut dоwn аll the trees оn the surrounding hills. Without trees to hold the soil in plаce, rain washed the soil into the harbor. So much silt accumulated in the harbor that large ships could not enter and Troy’s economy collapsed.

Good luck! Unless specifically asked, do not enter units for calculated answers as part of the answer. You will be prompted for the units that your *numerical answer* should be expressed in. In the event you need to use scientific notation to answer a question, use exponential notation, i.e., c = speed of light = 3.00 x 10^8 m/s = 3.00e8. Planck's constant = 6.626e-34 J/s. However, most questions should be structured such that you can just use standard numerical expressions.

Bond 1)___________________ is an uneven distribution of electronic charge along a covalent bond, which results from electrons being unevenly shared as a result of differences in attraction to each atom of the bond. This difference in attraction is the result of differences in 2)______________________, an idea proposed by Linus Pauling, which says that even formally charge-neutral atoms may attract electrons more strongly than others as a result of differences in atomic size and the the atom's valence shell energy level. In this way, such bonds may be 'in-between' the more idealized fully ionic and covalent sorts of bonds. The polarization of such bonds can be expressed with either 3)________________ notation, which is a way of expressing a partial positive or negative charge on the bonded atoms, or 4)_________________ notation, which 'points' from the more-positive to the more-negative of the atoms in the bond. The presence of such bonds may or may not render a molecule overall to show a similar charge-imbalance, known as a 5)__________________, depending on the geometry of the molecule and the way that individual bond polarizations add together.
