group. These groups make salicylic acid irritating because it burns the sensitive linings of the mouth‚ throat‚ esophagus‚ and stomach. 2 These harsh qualities are alleviated by replacing the acidic hydrogens with less reactive groups of atoms: the acetyl group (COCH3). This results in acetylsalicylic acid or "aspirin". Acetylsalicylic acid is synthesized in labs and does not occur naturally. It is produced from adding acetic anhydride to salicylic acid in the presence of sulfuric acid (H2SO4)‚ an

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

more profit. “Do the new supplements contain fillers such as sugar and starch or are they pure protein?” This is important because the consumers might be falsely informed on what they are actually putting into their body. We are trying to answer this because it will provide the consumers with accurate results of what contents are within these supplements. In our study we had four testing reagents (Lugol’s which tests for starch‚ Biuret tests for protien‚ Benedict’s that tests for reducing

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions
