(Name) (Course Name) (Instructors Name) (Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited

also have discrete energy levels‚ which can be considered as being packed on top of each electronic level. UV/Vis spectroscopy is routinely used in analytical chemistry for thequantitative determination of different analytes‚ such as transition metal ions‚ highly conjugated organic compounds‚ and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied. Solutions of transition metal ions can be colored (absorb visible light) because the
