The two alternative chair conformations of cis-2-bromocyclohexanamine differ in their gibbs free energy. using the data for δg (axial-equatorial) for monosubstituted cyclohexanes at room temperature (25ºc): axial → equatorial group δg° (kj/mol) group δg° (kj/mol) -0.8 -5.9 -2.4 -7.3 -3.9 1,2-gauche 3.8 calculate the absolute value of the difference in the gibbs free energy between the alternative chair conformations. kj/mol which group in this compound is in axial position in the energetically preferred chair conformation?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
