Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

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
