Through inspiration from the magazines, Mr. Asimov began to write short stories to share with his friends.…

dissolved in water, then there can be an understanding of the difference between the solubility because each chemical compound have different solubility even if they look similar. Materials: Equipment Chemicals Test Tubes (4) Water (H2O) Test Tube Rack Calcium Carbonate (CaCO3) Scoopula Candle Wax (CnH2n+2) (Paraffin Wax) Beakers Sodium Chloride (NaCI) Safety Goggles Sucrose Procedure: All equipment and…

clients to have plenty of space to walk around this facility; one on the right side between the area of locker room and restroom and close to the wall. Two power racks are located on the right upper side and provide multiple functions including stack the weights, pull up, rubber band variable exercises and others. A three-tier dumbbell rack that holds fifteen pairs of dumbbells from 10 lbs to 150 lbs with 10 lbs increment are on the upper side close to the wall of the main office. Five…

Isolation of Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask…

This lab experiment was completed to determine the environment in which microbes prefer to live. The pH, moisture, available nutrients, oxygen and light all affect the rate in which bacteria grow. The majority of bacteria flourish when the pH level is near neutral; the growth rate is highly affected if the pH is off by just a little. If too acidic, the amount of time it takes the bacteria to adjust to a new environment (lag time) is increased which slows the growth, the activity of enzymes is…

like metal and plastic, pickers put and storage into two places which are on floor and racking but the lowest part of rack and on floor is used to sort and put metal commodity, because metal commodity is heavy weight. If we put and sort on top rack of course, it’s hard to do so and also it will break the rack. For the plastic commodity can be put and sort on top of the part of rack or middle. The Order Picking system not only implemented in layout of pick area and zoning, but also in batching at…

Medieval Torture Medieval torture was one of the most inhumane things that has taken place in the history of the world. When thinking back to the medieval time period, there are several things that one should consider about medieval torture: the time period and innocent victims, the torture chambers and accused crimes, as well as the types of torture. "The medieval time period endured from the 400s to the 1300s or maybe even longer. Tens of thousands of innocent people lost their lives while…

solution and 1.5mL peroxidase into the ‘enzyme’ tube resulting in a total volume of 7.5mL. Cover and mix gently 4. Incorporate the substrate and the enzyme (with the pH solution) into one 16 x 150mL test tube. Cover, invert tube twice and put tube in the rack. Start timing the reaction promptly. 5. Over a 5-minute period observe any colour changes while being sure to rotate the tube before reading it. Record observations at 1 minute intervals 6. Reference the colour chart on page 156 of the AP…

The portions were then cut with a knife into 4-1cm pieces and taken back to our station. Each test tube was then labeled A,B,C,D and then again along the side of each test tube, measuring 6cm high. The test tubes were then placed into a test tube rack for visibility of all tubes along with keeping them safe during transport. We then filled each test tube with 6cm of water, shown by the mark made earlier on the test tube. One test tube and one piece potato was taken by each individual in the…
