One Cal is 3088 ft-lb of energy. Our leg muscles are about 20% efficient in converting the sugars into useful work, so to produce the energy above, a person will need to burn about five times that much Cal energy. How many Cal will the person burn during the 50-mi bike ride?

(28) Each bag of a manufacturer's candy contains 5 gumballs in no particular order. The gumballs are random assortments from among 4 different colors: red, orange, yellow, and green (R,O,Y,G). Examples: An (unordered) package of 5 gumballs might consist of: • 5-red; -or- • 2-green; 3 green; -or- • 2-red, 1-orange, 1-yellow, 1-green, -or- Question: How many of these different unordered combinations of colors are possible for each bag? Your answer must be in a format like, "515 different unordered combinations are possible."

The Michigan Advance Directive form that you'll need to fill out can be found under the "Files" tab or here: Michigan Advance Directive.pdf. Please take your time reviewing that document (especially the "Questions and Answers About Advance Directive" section) before filling it out. There you will understand the host of reasons that I'm having you fill these out as an assignment this semester. In brief, it's really helpful (and absolutely in-line with our ongoing course discussions about end-of-life ethics) to think through one's end-of-life wishes, to write them down, and to talk to your physician and loved ones about them even though we anticipate never needing to have that information readily available for any of us in the near future! In particular, you must only complete pages 28-39 and turn them back in. These pages must be filled out by hand and reuploaded if possible! Make sure you appoint a primary and secondary surrogate, that you adequately complete all the sections about end-of-life treatment options, and that you have two witnesses sign the document who are not involved in your healthcare or members of your family. Finally, every date must be the same on your completed Advance Directive! I have also uploaded a sample Michigan Advance Directive that is (unfortunately...) not entirely complete and is written by a Christian scholar who works in healthcare ethics (please make sure you read his disclaimer on the first page). For example, that sample AD does not have a secondary surrogate appointed, is not personally signed by Bill Davis (the scholar), and does not have signed witnesses either. Nevertheless, I thought you might find at least some example helpful as you fill yours out! That example AD can be found under the "Files" tab or here: Michigan Advance Directive (Completed by Bill Davis).pdf

MISSED THIS? Watch KCV: Finding pH and pH Changes in Buffer Solutions, IWE: Calculating the pH of a Buffer Solution as an Equilibrium Problem and with the Henderson- Hasselbalch Equation Read Section 18.2. You can click on the Review link to access the section in your eText. Use the Henderson-Hasselbalch equation to calculate the pH of each of the following solutions. Submit Previous Answers Correct Substitute the concentration of propanoic acid (acid) and potassium propanoate (conjugate base) into the Henderson-Hasselbalch equation to calculate pH: $\text{pH} = \text{p}K_a + \log\frac{[A^-]}{[HA]}$ $= 4.87 + \log\frac{0.115}{0.145}$ $= 4.77$ Part B a solution that contains 0.705 % $C_3H_5N$ by mass and 0.925 % $C_3H_5NHCl$ by mass (where $pK_a = 5.23$ for $C_3H_5NHCl$ acid) Express your answer using two decimal places.

A student performed the High Temperature Reaction in Part 2 of this experiment. They measured the initial solution temperature as 39.3°C and the final solution temperature as 39.1°C. Calculate the average solution temperature for this student's reaction in K, then calculate its corresponding value of 1/Temperature. Report your value for 1/Temperature as your answer, in K$^{-1}$, to 6 decimal places and only report the numerical value (no units). Do not use scientific notation to answer this question.
