Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

Pixar Facts 1.) In order to give Dash a realistic out-of-breath voice in "The Incredibles‚" director Brad Bird made actor Spencer Fox run laps around the studio.4 2.) Every Friday during the production of “Brave‚” each Pixar employee was told to wear a kilt for the fun of it. 3.) Shortly after completing Toy Story‚ the Pixar chief creative staff of John Lasseter‚ Peter Docter‚ Joe Ranft and Andrew Stanton got together for a lunch meeting at the Hidden City Café in 1994 that would become one of

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

Chemotherapeutic Agents of Control: Introduction: Chemotherapeutic agents are chemical substances used to treat various forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory.

The reaction process is shown by Figure 1 below. Equimolar amounts of sulfasalazine and cholinium hydroxide were mixed as a 45% solution in methanol. The sulfasalazine would ionise in the solution to form an ion‚ which would combine with the cholinium ion present in the solution to give the desired product. The methanol solvent was evaporated‚ and the remaining residue was dehydrated by vacuum. The product obtained appeared as a red glassy
