\({ }^{209 P}\) Po undergoes radioactive decay with a half-life of \(3.8\) hours by emitting alpha particles. Two moles of pure \({ }^{204 \mathrm{sip}} \mathrm{P}\) are isolated and put on a scale. After \(7.6\) hours a reading of the sample's mass is made. Its mass is found to be 1\. 201 grams. 2\. 203 grams. 3\. 400 grams. 4\. 402 grams.
Which of the following best describes the mechanism by which two substances form a maximum-boiling azeotrope? 1\. Each substance increases the specific heat of the other. 2\. Each substance decreases the specific heat of the other. 3\. Each substance increases the vapor pressure of the other. 4\. Each substance decreases the vapor pressure of the other.
All of the following are puzzling to reef scientists EXCEPT: 1\. how the zooxanthellae stimulate Scleractinia to secrete calcium carbonate. 2\. how barrier reef's become separated from land masses by vast expanses of water. 3\. how the reef environment reaches such high levels of oxygen saturation. 4\. how fringing reef's develop into barrier reef's and then into atolls.
Below is a plot of the temperature of the calorimeter versus time: cant copy graph Which point on the graph represents \(T f ?\) 1\. A 2\. \(\mathrm{B}\) 3\. \(\mathrm{C}\) 4\. D
Which kind of lamp, incandescent or fluorescent, is more efficient? 1\. Incandescent lamps, because they release all of the radiation they originally produce 2\. Fluorescent lamps, because they produce only radiation in the visible range 3\. Incandescent lamps, because no energy is lost in the conversion of energy from one wavelength to another 4\. Fluorescent lamps, because they multiply the intensity of radiation as it is converted from ultraviolet to visible light
