Draw the lewis structure of the azide ion that minimizes formal charge (it does not form a triangle). draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons. use square brackets to denote the overall charge.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
