Sustainable Chemistry
green chemistry - (answer)uses materials and processes that are intended to prevent or reduce pollution
at its source
replacing rare hazardous with more abundant less hazardous
Example of green chemistry - (answer)replacement of mercury fluorescent light bulbs with efficient
mercury free light bulbs

H fuel can then be reacted with O to produce heat and electricity
water---->hydrogen + oxygen
sustainable chemistry - (answer)designed to meet the needs of the present generation without
compromising the needs of future generations

Atomos - (answer)Lecuippus/democritus
point at which matter can no longer be subdivided
Mixtures - (answer)A combination of two or more substances that are not chemically combined
homogeneous mixture - (answer)a mixture that is uniform in composition; components are evenly
distributed and not easily distinguished
Ex: sugar and water
heterogeneous mixture - (answer)A mixture that is not uniform in composition; components are not
evenly distributed throughout the mixture
