TO STUDENTS:
Most of the lecture will be from this HTML notes and several PowerPoint Lecture notes. Some of the material in this HTML notes are based on "General Chemistry" (7th Ed., Ebbing & Garmon), the old textbook used prior to 2004.
Two PowerPoint Lecture Notes will complement this HTML notes: the first one is
a
modified version of the Power Point Slides
(by Prof. J.
D. Robertson)
an old
textbook
“Chemistry( 8th Ed., Raymond Chang)”
, the second one
being the
Power Point Slides
(by Prof. J.
D. BookStaver)
that came with
the current
textbook “Chemistry - The Central Science" (10th Ed., Brown, LeMay & Bursten).
50% of the lecture material will be selected from this HTML notes, another 50% will come from the Power Point Slides. In addition, these will be reinforced with some additional board work.
