Chemistry

Chemistry is a subject most people find difficult, somethings can be confusing and other just not make sense. To clear up some of these topics, past chemist have come up with laws. Three different laws to be exact, these laws were used and are still used to help people when combining elements. Each law is used for separate purposes composed by separate chemist; the first law is the law of definite proportions, the second is the law of conservation of mass, and finally the third is the law of multiple

Chemistry in the Real World As you walk down the street you are surrounded by chemistry. It is responsible for how many things work for example how your car gets you to school, how soaps clean you, and even how your cell phone charges. But one of the most profound and common chemical reaction that occurs is to formation of rust. Rust is a reddish-brown compound called iron oxide (Fe2O3). This is formed when iron is in contact with oxidant or acids. For iron to rust you must have water and oxygen

Day 1 and day 2 of the lab had a total of six parts: interpreting structures, roamers, recognizing isomers, conformation of cyclohexane, symmetry in chemistry and functional groups. By completing the different parts, I learned different and more complex things about organic chemistry. Part One of the lab was about interpreting structures. The two structures part one focused on was line, condensed and 3-D structure. Line structure is a representation of molecular structure where the bonds are represented

Module Nine: Lab Questions Your first lab link can be found at Forensic Drug Chemistry. 1. Why is chemical analysis used in forensic science? It's use so on any cases the evidence that was submitted at the lab that it was detected and we can help find out the types of illegal drugs, and helped the law enforcements officers or others stop offenders. 2. If you are working as a forensic scientist and are given an unknown powder from a crime scene, what would you hope to find out about the powder? I

Chemistry 310-Tools, Techniques, and Measurement Prelab Part A: Density of liquids and Weighing by Difference Obtain the mass of two dry and empty 125mL or 250mL Erlenmeyer flasks on a milligram balance and then number it. Record the mass in your data table. Get a 10.0 mL pipet and suction bulb then use deionized water to rinse the pipet. Then use the rinsed pipet to add 10.0 mL of deionized water to the flasks weighed previously. Then obtain the mass of the two flasks with the deionized water in

Starting from last year, the organic chemistry teaching lab in Tech has been my second home at Northwestern University. Soon, it became a place where I worked, researched, and studied. On some days, I would spend more time in the lab than in my own dorm room. This place was very familiar to me, but while observing this familiar place, I found different interactions that I had not noticed before. Prior to this observational exercise, I thought that the lab was a just place where classes were held

I selected organic chemistry because honestly it looks like a very interesting topic. Before doing research on this topic the knowledge I had before about organic chemistry was that it has something to do with food. After doing research I found out that I was way off track. I learned that in the late 1820’s was when organic chemistry was stumbled upon. In 1828 Friedrich Wohler produce the organic chemical rued, a mixture of urine from inorganic starting Materials. This is now called the Wohler Synthesis

The Chemistry of Smell In this paper I will be writing about the chemistry of smell. First and foremost I want to define exactly what smell is. Smell is the faculty or power of perceiving odors or scents by means of the organs in the nose. A smell can bring on an overflow of memories, influence people's moods and even affect their work performance but what actually is smell? Have you ever thought about it? Imagine trying to describe the smell of a rose to someone who has never possessed the ability

Clock reactions are among the most visually entertaining demonstrations of chemistry. Simply put, a clock reaction is one where two substances are mixed and there is a time delay where there is no visually discernable change in the system. During this delay, one of the chemical species, the clock chemical, has a very low concentration. The end of this induction period is marked by a rapid increase in concentration of the clock chemical (S.J. Preece et al., 1999). This rapid increase in concentration

Organic chemistry is the scientific study of organic materials, those that contain carbon atoms. Organic compounds are classified into families that are known as homologous series. The members of each homologous series share some common features. A homologous series is composed of compounds that have the same general formula (functioning group), usually the only differentiation is the length of the carbon chain or number of monomers. The difference in the length of the carbon chain can have an effect
