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?
Which of the four atoms Na, P, Cl, or K (a) has the largest atomic radius? (b) has the highest ionization energy? (c) is the most electronegative?
