On Greg's last visit to his doctor, he complained of feeling tired. His doctor orders a blood test for iron. Sandra, the registered nurse, does a venipuncture and withdraws 8.0 mL of blood. About 70% of the iron in the body is used to form hemoglobin, which is a protein in the red blood cells that carries oxygen to the cells of the body. About 30% is stored in ferritin, bone marrow, and the liver. When the iron level is low, a person may have fatigue and decreased immunity. The normal range for serum iron in men is 80 to 160 mcg/dL. Greg's iron test showed a blood serum iron level of 42 mcg/dL, which indicates that Greg has iron deficiency anemia. His doctor orders an iron supplement to be taken twice daily (b.i.d.). One tablet of the iron supplement contains 110 mg of iron. Part B Choose two conversion factors for one tablet of the iron supplement. Check all that apply. Iron 110mg iron 1g tablet

8. An instructor gave you directions to construct a model of the CH3CH2Br molecule by following t Experimental Procedure section of your experiment. First, you will need to find the number of valence electrons in CH3CH2Br. The number of va ence electrons in an atom of an element is said to be equal to the last d git in the group number of that element in the Periodic Table. How many sticks do you need if the electrons in the molecule are paired, and each post constitutes an electron pair? 9. An instructor gave you directions to construct a model of the CH3CH2Br molecule by following the Experimental Procedure section of your experiment. Now you assemble a skeleton structure for the molecule by connecting the balls with sticks into one unit. A ball has holes representing how many bonds an atom can form. You use the rule that C atoms form four bonds, while Br atoms usually do not. What is the sketch of the skeleton? 10. An instructor gave you directions to construct…

The compound hexaazaisowurtzitane is one of the highest-energy explosives known (C E News, Jan. 17, 1994, p. 26). The compound, also known as CL-20, was first synthesized in 1987. The method of synthesis and detailed performance data are still classified because of CL-20s potential military application in rocket boosters and in warheads of smart weapons. The structure of CL-20 is In such shorthand structures, each point where lines meet represents a carbon atom. In addition, the hydrogens attached to the carbon atoms are omitted; each of the six carbon atoms has one hydrogen atom attached. Finally, assume that the two O atoms in the NO2 groups are attached to N with one single bond and one double bond. Three possible reactions for the explosive decomposition ofCL-20 are i. C6H6N12O12(s)6CO(g)+6N2(g)+3H2O(g)+32O2(g) ii. C6H6N12O12(s) 3CO(g) + 3CO2(g) + 6N2(g) + 3H2O(g) iii. C6H6N12O12(s) 6CO2(g) + 6N2(g) + 3H2 (g) a. Use bond energies to estimate E for these three reactions. b. Which of the above reactions releases the largest amount of energy per kilogram of CL-20?

A combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Octane is a hydrocarbon that is found in gasoline. Complete combustion of octane produces 8 L of carbon dioxide for every 9 L of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?

Compared to their neutral atom counterparts, ions will have smaller or larger atomic radii due to their losing or gaining electrons. According to Jensen (2010), Linus Pauling assigned the radius of the oxygen anion (O“) at 140 pm (larger than the neutral atom, 66 pm). On the other hand, the magnesium atom loses 95 ppm from its 160 ppm radius when it loses two valence electrons, forming the magnesium ion.
