Schrodinger and de Broglie suggested a ‘Wave—particle duality" for small particles—that is, if electromagnetic radiation showed some particle-like properties, then perhaps small punicles might exhibit same wave-like properties. Explain. How does the wave mechanical picture of the atom fundamentally differ from the Bohr model? How do wave mechanical arbitals differ from Bohr’s orbits? What does it mean to say that an orbital represents a probability map for an electron?
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?
