Recall Robert H. Millikan's experiment to calculate the charge of a single electron. Millikan took single drops of oil with different amounts of
electric charge in them. He then calculated how much charge was
required to put into the bottom of the box to prevent the oil drop from
falling all the way to the bottom. By looking at his calculations he was able
to determine the amount of electric charge on a SINGLE electron. What
were the dependent and independent variable for this experiment and
what was the constant?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
