The figure shows (R,R)-1-ethyl-2-methylcyclohexane in one of its chair conformations. Draw the same compound in its other chair conformation. Follow this procedure.
Draw cyclohexane.Choose Edit ? Add ? Explicit H atoms.Press control-3.Press F7, or choose View ? Transform ? Rotate in 3D.Click and hold on the structure, and rotate it until you get a good view.Press control-A, press Cut, and press Paste.Type the name of an atom or group to add to the structure, or press the atom's button.Click on an H atom to replace that H atom with the atom or group at the tip of the cursor.
Do not delete any of the atoms or bonds in the ring or directly attached to the ring with the Erase button, and do not move atoms or groups directly attached to the ring by dragging them.
mass m in a one dimensional box of length L? If the answer is yes, then express the energy of this trial wavefunction in terms of h, m, and L?
Consider a solution formed by mixing 60.0 mL of 0.100 M H2SO4, 30.0 mL 0.100M HOCl, 25.0 mL 0.180M NaOH and 25.0 mL 0.100 M Ba(OH)2. Calculate the pH of this solution.
