Chemical Equation Chemical Reaction: C10H8+ 12 O2 → CO2 + 4H2 O (Naphthalene) Combustion Introduction of the Product: Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon‚ and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon‚ naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the

Choosing a major for my undergraduate degree was difficult because of all the options available to me. "Choosing a college major is an exploratory process that involves careful investigation and decision making". In the military I was trained to use a five step decision making process to solve problems. I used this process to choose the right major for me. "The first step in the decision making process was to make a self assessment". "The more you understand yourself‚ the clearer your

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

Acid Rain Lab Report Introduction: The problem was to see how crushed chalk and whole chalk weather differently. The independent variables are The temperature of the liquids The surface area of the chalk‚ crushed vs whole The dependant variable was the weathering of the chalk; this was calculated by measuring the foam reactant. Procedure: Part B- For the two partners recording data with the room temperature liquids‚ the materials where collected first. Two of the graduated

Clock reactions If you choose a project that explores the kinetics of a chemical reaction you will need a way of measuring the rate of the reaction. Clock reactions provide an interesting way of doing this for some systems. In a typical reaction the first part of a graph showing the concentration of product against time is approximately a straight line (see Figure 1). If you choose any value of concentration that lies on this straight line (say c1) the initial rate of reaction can be found
