Experiment 4: Preparation and Properties of Hydrogen and Oxygen Gases Toriana Mieer -Jones Name: Section: Lab Instructor: L/26 Date: Pre-Lab Exercise 4 1. In this experiment, simple chemical reactions are used to generate small quantities of hydrogen and oxygen gases. These methods would be too expensive and too complicated if large quantities of these gases were needed, however. Use your textbook, a chemical encyclopedia, or an online source to look up the major industrial methods of preparing very large quantities of these gases. Summarize your findings here. ono od te led bateono to n

3) You're wandering around and come upon an interesting looking rock. The rock is slightly radioactive, so you analyze it. The resulting data is as follows: Elapsed Time (s) Counts 962 50 891 100 718 150 598 200 531 250 448 300 413 350 334 400 308 450 287 500 202 550 178 600 154 a. Calculate the value of k using any two of the above data points. b. Use your value of k to determine the half-life of this sample.

4. For each case, draw at least one possible constitutional isomer that is consistent with the molecular formula and the IR spectrum.

Try Again Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. A certain drug has a half-life in the body of 3.5 h. Suppose a patient takes one 300. mg pill at 7:00PM and another identical pill 45 min later. Calculate the amount of drug left in his body at 10:00PM. Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits. 559. mg x10 X
