    phantoms coupled with the fact that the biological tissues are porous in nature consisting of numerous blood vessels of various diameters‚ make the job of determination of the laser intensity distributions extremely difficult. The Radiative Transport Equation (RTE) developed by Chandrasekhar [4] has been employed in the present work to solve for the light transfer inside the tissue phantoms. The RTE model‚ developed by Chandrasekhar [4] has been developed by considering a balance of photons inside a control

    and different techniques are created. In chemical analysis‚ the amount of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009)

    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

    Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone
