Two SPHA032 students were arguing during lunch at the university of Limpopo cafeteria about whether Niobium (Nb) is a BCC or FCC structure. In order to help them resolve their argument determine yourself whether Niobium is BCC or FCC by calculating the density of Nobium given that its density is 8.57 g/cm³ with radius 1.43 X 10 cm, and its atomic weight is 92.91 g/mol. Use provided constants and the periodic table attached

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?
