Introduction: Chemical methods of control: Antimicrobial drugs‚ involves the use of chemicals to prevent and treat infectious diseases. Pasteur and others observed that infecting an animal with Pseudomonas aeruginosa protected the animal against Bacillus anthracis. Later‚ the word “antibiosis” (against life) for this inhibition and called the inhibiting substance “Antibiotic”. As researchers found out more and more about these chemicals they were able to discover that antibiotics are chemicals or

Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that
