30. (Ill) The dipole moment, considered as a vector, points from the negative to the positive charge. The water molecule, Fig. 17-28. has a dipole moment p which can be considered as the vector sum of the two dipole moments. Pi and p2, as shown. The distance between each H and the O is about 0.96 X 10_,m. Itie lines joining the center of the O atom with each H atom make an angle of 104, as shown, and the net dipole moment has been measured to be p = 6.1 x 10_3oC-m. Determine the charge q on each H atom.

January 23 rd Atoms and molecules adopt shapes that maximize the distance between valence electron pairs. Ex: Methane (CH ) 4 - For 4 electron pairs, maximal distance occurs as a tetrahedral shape. - All bond angles in this shape are 109.5 degrees. But about the...
