1. Ammonia (NH3) to ammonium (NH4+) comparison. N basis orbitals 2sp3 a1 H basis orbitals linear combinations e 1s e a1 a1 a1 3 bonds, 1 lone pair a. Look at the HOMO in the NH3 MO diagram (this is the N sp³ hybridized version shown in the lecture slides). Visualize a H+ coming to react with the NH3. To which atom will it be attracted? Explain why, with reference to the MO diagram. b. After the NH4+ ion forms, which of the MO diagrams in the lecture PowerPoint slides should be used to describe it (choice of BeH2, BH3, NH3, CH4)? Why? c. Based on the MO diagram chosen, predict whether we can distinguish the new N-H bond from the previous three N-H bonds. Why or why not?

Three years ago, you invested $12,000 in a certificate of deposit (CD) with a bank, which promised to pay compound interest of 3.5% per year. Interest rates have gone up since then, and this year you'll be able to reinvest your money (the amount you invested in the original CD, plus all of your interest earnings) into another CD, which will pay 5.5% compound interest per year, for the next two years. Given these interest rates, what will be the total value of your investment (i.e., how much money will you have) when the second CD matures (ends) two years from now? Show steps using BAIIPlus calculator functions.

As shown on the image, a horizontal plate is supporting a chest with the mass of 100 kg. Coefficient of friction between the chest and the plate is f = 0.3. What force would be required to act on the chest to accelerate it to 3 m/s$^2$ from the rest? Your answer should be with two decimal points accuracy.

Linear Regression In summary and in general, $m = \frac{n \sum_{i=1}^{i=n} x_i \cdot y_i - \sum_{i=1}^{i=n} x_i \sum_{i=1}^{i=n} y_i}{n \sum_{i=1}^{i=n} x_i^2 - (\sum_{i=1}^{i=n} x_i)^2}$ (1) OPTIONAL HOMEWORK: • Deduce the formula in equation (1) (Algebra homework). • Make a code in (Python, Matlab, Excel...) that computes the value of m and b from a dataset (For instance, use Premier League dataset). • Find real applications of the linear regression problem applied to your major. (gen. ed. homework).
