Part A) Place the following elements in order of increasing atomic radii: Mg, Na, Rb, Cl. Part B) Balance the following oxidation-reduction reaction: NH3(g) + O2(g) => NO(g) + H2O(g) The sum of all the stoichiometric coefficients in the balanced equation is: (a) 4 (b) 7 (c) 10 (d) 19 (e) None of those, if so what is your answer Part C) A freighter carrying a cargo of uranium hexafluoride sank in the English Channel in late August 1984. Uranium hexafluoride was contained in 30 drums, each having a volume of 1.62×106 L. Uranium hexafluoride density is 5.09 g/mL. What was the mass (in ton, 1 ton=1000 kg) of sunk UF6? a) 47×105 b) 9.43×107 c) 2.47374×105 d) 0.247 (e) None of those. If so, what is your answer?
