165mL acetic anhydride and a magnetic spin vane. An air condenser was attached to the vial and it was heated on an aluminum block‚ with a temperature maintained at 120C. After the solution dissolved‚ it was heated an extra 20 minutes to allow the reaction to go to completion then cooled back to room temperature. An ice bath was used to encourage crystal growth. The crystals were removed and centrifuged‚ then placed on a pre-weighed watch glass to dry and weigh. Percent recovery was found. A small

The Displacement Reactions Purpose: to see how displacement reaction works with different chemicals and what chemical has more reactivity series then other Hypothesis: Iron + Copper Sulfate: Iron will displace copper because it is more reactive and it is going to end up as Iron Sulphide + Copper Copper + Silver Nitrate: Copper will displace Silver because it is more reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck and Stille reactions. Palladium typically exists in the oxidation
