Draw the structure(s) of the major organic product(s) of the following reaction. Ethanol / trace of HCl $0^\circ C$ Use the wedge/hash bond tools to indicate stereochemistry where it exists. If the reaction produces a racemic mixture, draw both stereoisomers. Include counter-ions, e.g., $Na^+$, $I^-$, in your submission, but draw them in their own separate sketcher. Omit products derived from the acidic or basic reagent itself, e.g. $HN(i-Pr)_2$ derived from $N(i-Pr)_2$. If substantial starting material is present at the end of the reaction, include it in the products. If no reaction occurs, draw the organic starting material. Draw the structure(s) of the major organic product(s) of the following reaction. 1 eq. $Cl_2$ Acetic acid Use the wedge/hash bond tools to indicate stereochemistry where it exists. If the reaction produces a racemic mixture, draw both stereoisomers. If no reaction occurs, draw the organic starting material. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple products using the + sign from the drop-down menu. Draw the structure(s) of the major organic product(s) of the following reaction. 2 eq. $CH_3I$ / aqueous $NaHCO_3$ You do not have to consider stereochemistry. Omit products derived from the acidic or basic reagent itself, e.g. $HN(i-Pr)_2$ derived from $N(i-Pr)_2$. If no reaction occurs, draw the organic starting material. If substantial starting material is present at the end of the reaction, include it in the products. Draw one structure per sketcher.

14-21. Suppose that the concentrations of NaF and KCl were each 0.10 M in the cell Pb(s) A PbF2(s) A F2(aq) B Cl2(aq) A AgCl(s) A Ag(s) (a) Using the half-reactions 2AgCl(s) 1 2e2 Δ 2Ag(s) 1 2Cl2 and PbF2(s) 1 2e2 Δ Pb(s) 1 2F2, calculate the cell voltage. (b) In which direction do electrons fl ow? (c) Now calculate the cell voltage by using the reactions 2Ag1 1 2e2 Δ 2Ag(s) and Pb21 1 2e2 Δ Pb(s). For this part, you will need the solubility products for PbF2 and AgCl.

The Air Force expects to modernize its combat arsenal. It plans to acquire 12 fighter planes of three different types (identified as A, B, and C) depending on the range of action. The Federal government has allocated a budget of 900 million dollars for this purpose. What should be the number of acquired aircraft of each type, knowing that an A-type fighter costs $30 million, a B-type costs $50 million, and a C-type costs $90 million? Use the Gauss-Jordan method as a solution method.
