Electrophilic Aromatic Substitution Objective The objective of this experiment was to illustrate electrophilic aromatic substitution by synthesizing p-nitroanilide (as well as ortho) from acetanilide by nitration. The para form was separated from the ortho form based on solubility properties using recrystallization techniques. Synthetic equations: Physical Properties & Hazards of Reagents/Products: (all taken from Sigma-Aldrich website) Acetanilide MM = 135.16 g/mol Melting point =

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables

Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same
