Five grams of contaminated soil were digested in 100mLHNO_(3) solution and the concentration of Cu^(2+) ion in the digested solution was 128 ppm (atomic weight of Cu=64 ). Please solve the following problems: a. calculate Cu concentration of the digested solution in moles/L b. compute the ppm (i.e., \mu (g)/(g) ) of Cu in the soil c. what is the meq of Cu^(2+) in this 100 ml solution?

15. Consider the system x' = Ax, and suppose that A has one zero eigenvalue. a. Show that det A = 0. b. Show that x = 0 is a critical point and that, in addition, every point on a certain straight line through the origin is also a critical point. c. Let $r_1 = 0$ and $r_2 \neq 0$, and let $\xi^{(1)}$ and $\xi^{(2)}$ be corresponding eigenvectors. Show that the trajectories are as indicated in Figure 9.1.7. FIGURE 9.1.7 Trajectories for a linear system with nonisolated critical points, that is $r_1 = 0$ and $r_2 \neq 0$. Every point on the line through $\xi^{(1)}$ is a critical point. What is the direction of motion on the trajectories? What determines the direction of motion along a trajectory?

Texts: The example in Section 3.1.4 simulated sampling distributions of the sample mean to determine how precise Ȳ for n = 25 may estimate a population mean µ. a) Find the theoretical standard error of Ȳ for the scenario values of σ = 5 and 8. How do they compare to the standard deviations of the 100,000 sample means in the simulations? Your answer goes here [ ]: b) In the first scenario, we chose σ = 5 under the belief that if µ = 20, about 2/3 of the sample values would fall between $15 and $25. For the gamma distribution with (µ, σ) = (20, 5), show that the actual probability between 15 and 25 is 0.688. Python code needed.

5. For each of the factors listed below, describe how being immersed in hot water, consuming alcohol and taking Lasix, would affect each and why. Limit discussion of alcohol to the immediate effects on the CNS, and make sure to follow the example answer! (6 pts) Effect of hot water Effect of alcohol Effect of Lasix Peripheral reduced by heat due to resistance vasodilation response to cool core temp reduced by alcohol which inhibits vasoconstriction due to depression of CNS and sympathetic output No direct effect Heart rate Stroke volume

Paragraph Yesterday, on Monday, October 10, 2022, most features of Word will be disabled. Reactions: NH2 .0: O. p-aminophenol acetic anhydride acetaminophen acetic acid mw: 109.13 g/mol mw: mw: 0.67 g/mol density: 1.13 g/cm^3 d: density Detailed yield calculation: Type equation here. Melting point data: A short paragraph summarizing results of crude acetaminophen. The melting point of crude acetaminophen when heated rapidly is 170 degrees Celsius, but when slowed down, it begins at 168.88 and ends at 169.4. As can be seen, there is a slight difference of two degrees, but it does fall towards the 170 degrees Celsius. b) Melting point of recrystallized acetaminophen: The melting point of recrystallized acetaminophen when heated rapidly goes up to 170 degrees Celsius. When my partner and I went slow, it started to melt at 169.1 and completely liquefied at 170.7 degrees Celsius. There was a slight difference of 1 degree Celsius. Literature of acetaminophen with source: When I looked at a source with the melting point of acetaminophen, it ranges from 168-172 degrees Celsius. I found this source at https://www.futureengineers.org/namethatmolecule/gallery/3201. D Assigned questions from Pavia lab text: Page 86 Text Predictions: On Focus Here to search Hi

5. A three-phase synchronous motor has an output power of 100 hp and operates at a speed of 1800 rpm. The motor is supplied from a three-phase voltage source of 460V, 60 Hz. The motor's core loss is 4kW, the copper loss is 3 kW, and the rotational losses are 1kW. The stray load losses are negligible. The motor is operating at 0.9 pf and the motor is overexcited. (a) Determine the real power supplied by the three-phase voltage source [kW]. (b) Determine the reactive power supplied by the three-phase voltage source [kVAR]. (c) Determine the motor's efficiency [%]. (d) Determine the magnitude of the line current of the motor [A]. (e) If the mechanical load connected to the motor were abruptly disconnected, what would you expect the motor's speed to become? [rpm]
