Date: 25th November‚ 2011 Aim: To show that when Hot and Cold water are mixed‚ heat lost by hot water is equal to heat gained by cold water. Theory: This Lab is done to demonstrate “the Law of Conservation of Energy”‚ which implies: - “the heat lost by one (1) substance must be equal to the heat gained by another substance within the system”. Apparatus: Two (2) similar Calorimeters: a Thermometer: a Measuring Cylinder: a Bunsen burner: a Tripod: an Asbestos Gauze Cork Mat. Procedure:

Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

In order to conduct this experiment GIY Mushroom Material was obtained. All other materials were cleaned with rubbing alcohol‚ (70% Isopropyl Alcohol). Rubbing alcohol was used because mycelium needed a sterile environment (7). Everything was sprayed with alcohol including tables‚ gloves‚ mixing glass‚ and even the air. All materials used were cleaned because it protected the mycelium from competing with other organisms. Mold could have been floating in the air or bacteria from touching the face

The lab in which we conducted last Tuesday was an analysis of a hydrate and what happens to it when it is heated. A hydrate is a crystalline compound which water molecules are chemically bound to it. In the lab‚ we were to analyze the difference in grams of the hydrate and the anhydrate. An anhydrate is the crystalline compound without the water molecules bound to it. During our lab‚ we were to heat up the crucible‚ the crucible with hydrate‚ and the crucible with an anhydrous and write down each

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here
