Assume that a system has a very large number of energy levels given by the formula εl=ε0l2εl=ε0l2 with ε0=1.25×10−22Jε0=1.25×10−22J, where ll takes on the integer values 1, 2, 3, . . . . Assume further that the degeneracy of a level is given by gl=2lgl=2l.
Calculate the ratio n2/n1 at 250. K.

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
