2. The molecule buta-1,3-diene is an easily isolatable gas with a normal boiling point just below the freezing point of ice. Cyclobuta-1,3-diene, however, is a very unstable molecule that can only be isolated below 35 K (-238 °C). a. (1) Draw two molecular orbital (MO) diagrams, one for (a) cyclobutadiene and one for (b) buta-1,3-diene. For each energy level in each diagram, (ii) draw a p-orbital representation of the MO that corresponds to that energy level. Be sure to (ii) shade your orbitals appropriately and (iv) draw any and all nodes. Next, (v) label each orbital as bonding, non-bonding, or anti-bonding and briefly (vi) explain how you made those determinations. Finally, (vii) show how many electrons fill each orbital. b. Using the MO diagrams you just prepared, (i) explain why there is such a difference in stability between the two compounds buta-1,3-diene and cyclobuta-1,3-diene. As part of your answer, be sure to (i) explain why cyclo-1,3- butadiene cannot exist at room temperature

Household vinegar is a dilute solution of acetic acid. A sample of household vinegar was measured to have a hydronium ion concentration of 5.8 x 10-3 mol/L. Determine the pH of the sample. Do not show your work. Record only your final answer with the correct number of significant digits. Remember, pH does not have units! Hand soap is effective at preventing bacterial contamination. Calculate the hydronium ion concentration in a brand of hand soap with a pH of 10.5 You MUST show your work. Record your answer in scientific notation with the proper significant digits and units.
How is BOD removed from wastewater?
