a)
The water molecule consists of two hydrogen atoms and one oxygen
atom. Since the oxygen atom has a higher electronegativity than the
hydrogen atom, the side of the molecule with the oxygen atom has a
partial negative charge.
Assume that the partial positive charge on each hydrogen atom is
Q2 = 0.512 x 10-19 C. What is the
electric charge Q1 on the Oxygen atom?
b)
The water molecule forms an angle, with hydrogen atoms at the
tips and...
