Water is Special Polarity There are two types of covalent bonds, polar and nonpolar While nonpolar molecules share electrons equally, polar molecules do not. This results in one part of the molecule being partially positive and another part being partially negative. 2 Student Misconceptions and Concerns

Eugene LeMay, Jr.; and Bruce E. Bursten Atomic Theory of Matter The theory that atoms are the fundamental building blocks of matter reemerged in the early 19th century, championed by John Dalton. Dalton?s Postulates Each element is composed of extremely small particles called atoms. Dalton?s Postulates All atoms of a given element are identical to one another in mass and other properties, but the atoms of one element are different from the atoms of all other elements. Dalton?s Postulates

Photosynthesis Wednesday, March 06, 2013 11:00 PM ? Photosynthesis Photosynthesis - the process of converting energy in sunlight to energy in chemical bonds, especially glucose 6CO2 + 6H2O + light -> C6H12O6 + 6O2 Begins with light-absorbing pigments in plant cells A pigment molecule is able to absorb energy from light only within a narrow range of wavelengths In order to absorb as much of the entire bandwidth from sunlight as possible, different pigments, capable of absorbing different wavelengths, act together to optimize energy absorption These pigments include the green chlorophyll a and chlorophyll b and the carotenoids, which are red, orange, or yellow
