9. Calculate the change in enthalpy of formation when dihydrogen sulfides is bubbled through basic solution, given that the heat of formation of each is: H S = -20.6 kJ/mol, KOH -482.37 kJ/mol. H.O-285.8 kJ/mol, KS-406.2 kJ/mol. H.S (g) - KOH(aq) - - H.0 (- KS (aq)
Find an example of Oxime preparation via a conventional heating method from literature and comment on how it differs from using a microwave. Discuss how oximes can be cleaved.
Briefly describe basic chemistry of the following human body processes in 30-40 words each) and provide one (1) example of chemical reaction related to each. Metabolism Respiration
Exercise 4-13 Missing Data; Basic CVP Concepts (LO5-1, LO5-9) Fill in the missing amounts in each of the eight case situations below. Each case is independent of the others. (Hint: One way to find the missing amounts would be to prepare a contribution format income statement for each case, enter the known data, and then compute the missing items.) points Required: a. Assume that only one product is being sold in each of the four following case situations: Skipped Case...

I need an example of a basic Java introduction() method for MyClone class providing first and last name and statement ,
Find and describe an example of both an acidic buffer, and a basic buffer. Indicate where each buffer is found or used, and include a calculation of [H+], [OH-], and pOH for each buffer. Your response should be at least two paragraphs. Provide citations and references.
7. Describe one example of how fruit color affects foraging behavior in animals 8. There are three mechanisms to avoid self fertilization (temporal, spatial, and self-incompatibility). Describe one example of each of the three mechanisms. 9. Describe how flowers attract different types of pollinators (e.g. bees, flies, moths bats, birds, etc). Choose at least three different pollinators. 10. Explain why a flash of light during the night would prevent flowering in a short- day plant, but wouldn't prevent flowering in...
