In the precipitation step of Experiment 2, we used 12 M HCl, however, in the extraction we used 3 M NaOH. Why was a concentrated acid used to recover the benzoic acid, but a dilute base for the extraction? Your discussion should address safety, the concentrations of these solutions, and their purpose in their respective techniques. Your answer in question 2 should inform some of your discussion. Discussions should be made in five sentences or less.

Nicole was writing an essay on how short-term memory works. She wrote, "Information is first maintained in the phonological loop. It is then passed to the visuospatial sketchpad where you can temporarily store images and spatial information. Then it moves on to the episodic buffer where information can be integrated and manipulated. Finally, information is passed to the central executive where allocation of attention and action is considered. All of this has to be done very quickly because information can be lost in short-term memory after 60 seconds if not processed." What mistake did she make? A. There is no visuospatial sketchpad B. The phonological loop occurs after the visuospatial sketchpad C. The episodic buffer occurs before the central executive D. The retention time for short-term memory is only about 18 seconds E. These processes all occur in parallel, not a linear timeline

D. (11%) Find the general solution of the given differential equation y^(4) - y'' = x + 2 11. (5 Extra Points) An 8-pound weight stretches a spring 2 feet. Assuming that a damping force numerically equal two times the instantaneous velocity acts on the system, determine the equation of the motion if the weight released from the equilibrium with an upward velocity of 3ft/s.

3. A single-phase 2200/220V, 50Hz transformer draws a no-load current of 0.6A at power factor 0.303 lagging when connected to a 2200V supply. With the aid of a phasor diagram, calculate (a) The magnetizing current, (b) The core-loss current, (c) The magnetizing reactance, and (d) The core-loss resistance. 4. A single-phase transformer has 2400 turns on the primary and 600 turns on the secondary. Its no-load current is 4A at a power factor of 0.25 lagging. Assuming that the voltage drop in the windings is negligible, calculate the primary current and its power factor when the secondary current is 80A at a power factor of 0.8 lagging.
