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

Reaction Paper On The Ice is an engrossing and suspenseful movie about two teenage boys. The boys grew up together in the town of Barrow‚ Alaska. One morning the boys (Qalli and Aivaaq) set out for a seal hunt with a friend (James). An argument took place that ended up in a tragic accident. The boys (Qalli and Aivaaq) promised to keep this a secret. The community began asking questions‚ which brought them telling one fabrication after another which lead to feeling more guilt.

similarity between the value of the sum for Reaction 1 and Reaction 2’s change in temperature‚ compared to Reaction 3’s change in temperature. Reaction 1 was the dissolution of solid sodium hydroxide in water with a ΔH°rxn of -47047 J/mol‚ Reaction 2 was the neutralization of liquid sodium hydroxide with HCl with a ΔH°rxn of -31289 J/mol and Reaction 3 was the dissolution and neutralization of solid NaOH with HCl with a ΔH°rxn of -91000 J/mol. Consequently‚ the sum of Reaction 1 and Reaction 2 was -78336

precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or

Experiment 3: Wittig Reaction Introduction This experiment performs a modified Wittig reaction using a phosphorus-containing Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by
