However, my initial interest was actually mechanical engineering because I liked to build and design things. This was changed when I took College Chemistry one and two in high school. I had also always had an interest in chemistry and chemical reactions, but as I learned more about the processes involved and about how chemistry actually works I knew that chemical engineering would be the right career path for me. It combines both chemistry and engineering new and innovative processes on a large…
slow the spread of the cancer throughout the body. These scientific applications still have both strengths and limitations. Strengths include a better understanding of negative reactions to avoid future problems as well as the discovery of results both positive and negative through experimentation, such as the chemical reactions of cyclophosphamide to slow cell division in relation…
the sodium thiosulfate solution the faster the reaction, causing the cluster of data later on in the graph. This is due to the high temperatures causing the increase in the particles average kinetic energy, the more energy provided by the heat of the water baths the faster the particle within the solution are able to move. As a result of the increased movement the particles are more likely to collide in the correct orientation and cause a faster reaction to occur. As the temperature reaches room…
specific substrates to achieve an highly effective catalyst reaction. .Almost all cellular activities of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts,enzymes provides another reaction route requires lower activation energy (Ea) to increase the number of particles that have a kinetic energy of not less than the activation energy, thus speeding The reaction rate. Most of the reaction rate can be improved hundreds of times by…
Chemical kinetics are governed by the mathematics of systems of differential equations (Thermodynamics and Kinetics). This means that the rate of any chemical reaction is determined by the type, and amount, of reactants present. Note the rate of a reaction is how fast it occurs. Furthermore, such rate equations can either be distinctively linear or non-linear when graphed. Non-linear equations are supposedly more complex as they generally react to small changes within its parameters…
It is important to study reactions to queue jumping simply because of the social implications that are derived from this, as understanding how people function within a social in-group and how they react to an out-group can be vital. Through this knowledge one may able to apply this…
with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between 7.0002g of copper(II)sulfate and 2.0101g iron metal which produced 2.3037g of copper product with a percent yield of 100.72%. Introduction: Much research has gone into studying how to best utilize the degradation abilities of…
cells. This lab explores how catalase reacts to four different temperatures and how the concentration percentage of substrate affects its reaction rate. The performance of catalase is dependent on many factors, so the purpose of the lab was to find the ideal concentration and temperature for catalase. We hypothesized that catalase would have the fastest reaction at its preferred temperature and at the highest substrate concentration. The results revealed that catalase, in fact, did perform…
In Heather E. Douglas’s essay “The Dark Side of Science”, she mentioned that scientists should be responsible for their discoveries that are used to the awful advantages that they could be used for. Scientist who makes these discoveries may know what they can endure. Scientist usually knows how there discovers will end up, but mostly they do not think of the reproductions that could happen if they ended up being used for the wrong intended purposes for that particular discovery. Douglas writes…
Analysis of Galvanized Nails, Quality Control, and Green Chemistry Introduction: In this lab, we handled acidic chemicals that needed to be disposed of upon completion of the lab. We disposed of these chemicals according to safety policies and green chemistry policies. Green Chemistry is the practice of chemistry in an environmentally safe way to prevent pollution. We used green chemistry to minimize the amount of waste we were to be creating. We ended up creating waste from degalvanizing…
