4. Use the DISK method to find the volume of the solid obtained by rotating the region under the curve               y = x3 from x = 0 to x = 3 about the x-axis. Draw a typical DISK in order to document your work properly.             

For the dominant Lewis structure of CO32−, the VSEPR model predicts that, around the central atom, the electron domain geometry (EDG) is                     and the molecular geometry (MG) is                      .

Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is an active component of chili peppers, which produces a sensation of burning in any tissue with which it comes into contact. In the Lewis structure for capsaicin shown below, what are the approximate bond angles for the angles labeled d and g?

For the dominant Lewis structure of BrF5, the VSEPR model predicts that, around the central atom, the electron domain geometry (EDG) is                     and the molecular geometry (MG) is                      .
