Abstract The purpose of this experiment was to react 2-methyl-2-butanol with concentrated HCl in order to form 2-chloride-2-methylbutane. The hydrogen for the HCl make the -OH from the 2-methyl-2-butanol into a good leaving group because H2O is formed. The H2O leaves and Cl- is free to bond with the carbocation creating 2-chloride-2-methylbutane. The materials needed for the lab were an Erlenmeyer flask with a stir bar‚ the stirring function of the hot plate‚ an ice bath‚ a separatory funnel‚ and

Yet we’re forgetting that somewhere in that time frame‚ around the 1970’s a music form known as reggae emerged from the little island of Jamaica‚ and with it came a man that will never be forgotten. His name was Robert Nesta Marley although he was better known to us as Bob

Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists of one oxygen bonded singularly to

equation for photosynthesis is 6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O. This means its reactants are 6 parts CO2‚ 12 parts H2O‚ and light. When combined in those proportions‚ they become 6 parts O2 and 6 parts H2O (After going through photosynthesis). The overall equation for aerobic respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy. This means its reactants are one part C6H12O6 and 6 parts O2‚ while the products are 6 parts CO2‚ 6 parts H2O‚ and energy (After going through aerobic
