12. The daily does of ampicillin for treating an ear infection is 0.100 g per kg of body weight. What is the daily dosage for a 22 pound child with an ear infection? [1 kg-22 lb) A) 4.55 kg B) 45.5 mg C) 2.2 mg D) 1000 mg 13. Which are the correct formulas for solid magnesium chloride and gaseous oxygen? A) MgCl (s) and O (g) C) MgCl (s) and O₂ (g) B) MgCl₂ (0) and O (g) D) MgCl (s) and O₂ (g) 14. Potassium chlorate, KCIO,, is decomposed in a test tube by heating until all the oxygen is released. The chemical reaction that occurs is 2 KCIO, ()2 KCl (s) +30, (g) Which of the graphs shown below best represents the change in mass of the test tube and its contents? B) D) EFER Mass Time 15. Select the best answer from the choices given. The two letters to the editor shown below are responses to an article in a scientific journal that suggested exposure to electromagnetic fields generated by high-tension power lines is a health hazard. Both writers find fault with the scientific method used in the original study. In particular, the writers of both letters feel that the original study A) did not control all the variables associated with the experimental data. B) did not formulate an hypothesis. C) involved too many experiments. D) None of the above. Power companies here in northern New England periodically apply chemical berbicides to limit weed growth under the towers that carry the lines. I wonder if the power companies in Los Angeles do the same thing and whether this "other EMF factor has been studied in epidemiological studies. L. Carl Pederson Hanover, NH Perhaps the EMFs are indirectly involved in cancer induction: high-tension wires apparently fis nitrogen, as demonstrated by the especially lush, green grass that grows under them in fields. Related chemistry might create or activate air- or water-borne carcinogens. I suppose this hypothesis could reconcile the inconsistent conclusion of epidemiological studies, particularly if a trace reactant such as formaldehyde were involved. George Meitmer Pittdown, NJ
