Chemistry 12 Unit 1 - Reaction Kinetics Chemistry 12 Worksheet 1-3 - Reaction Mechanisms 1. It is known that compounds called chlorofluorocarbons (C.F.C.s) (eg. CFCl3) will break up in the presence of ultraviolet radiation‚ such as found in the upper atmosphere‚ forming single chlorine atoms: CFCl3 CFCl2 + Cl The Cl atoms then react with Ozone (O3) as outlined in the following mechanism. Step 1: Step 2: Cl + O3 ClO + O2 ClO + O Cl + O2 (single "O" atoms occur naturally in the atmosphere

C.S. Lewis According to author‚ scholar‚ and Christian apologist C.S. Lewis‚ “The task of the modern educator is not to cut down jungles‚ but to irrigate deserts” (this is what Lewis said when he wrote The Abolition of a Man).

Purchase to be mapped out. Jefferson sent Lewis and Clark to do this for him. Lewis wrote to his friend and former Army colleague‚ William Clark‚ and invited him to join the expedition as co-leader. Clark‚ then living in Kentucky‚ wrote back: “This is an undertaking fraited with many difeculties‚ but my friend I do assure you that no man lives whith whome I would perfur to undertake such a Trip.” The journey began as Lewis left Washington D.C. on July 5‚ 1803 and ended

Chemistry and cosmetics Cosmetics have been around since almost the beginning of time. Egyptian women used kohl to darken their eyelids‚ Cleopatra was even said to have bathed in milk to achieve a soft smooth completion. In Greece‚ women used lead carbonate (a white powder) to obtain a pale complexion‚ which probably wasn’t worth it seeing how it cost them their lives! Anyway‚ cosmetics are no modern phenomenon! Today it is a big business‚ making about $12 billion

Pacific Ocean . During the trip‚ we found a land called Spirit Mound 6 miles north of the river. Lewis and Clark took several men and hiked a few hours north of the river. Their goal was to investigate an isolated hill on the prairie rumored to be inhabited by fierce spirit people who were 18 inches tall. They had remarkably large heads and could through shafts across a great distance to kill. Lewis and Clark took several men and hiked a few hours to get there The land also had
