ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

Legal protection and conservation plan for these endangered subspecies should be established. However‚ organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Biologists group and classify living and extinct organisms for many reasons such as to establish a common language or
