Hydrocarbon

hydrogen peroxide, superoxide, and hydroxyl radicals (13, 14).Benzene and related hydrocarbons are metabolized through an intermediate epoxide, which is highly reactive and possibly binds to hepatic microsomal proteins and nucleic acids leading to cytotoxic effects (15). An increase in the levels of liver diagnostic parameters in this study might be due to toxic effect on the membrane of liver cell where petroleum hydrocarbons may have been converted into free radicals or activated metabolites…

Dr. Andrzeij Sygula Research Dr. Sygula research is on polycyclic hydrocarbons called buckybowls. Due to their non-planarity, these moleules resemble fragments of fullerene, hence the name buckybowl. The smallest buckybowl to date is coronnulene, a non-planar hydrocarbon made up of five overlapping 1, 3-cyclohexadiene rings figure 1. The synthesis of coronnulene in lab is very challenging primarily because of the stress associated with the non-plannar molecule. Dr. Sygula’s lab accidentally came…

1.1 Overview: In a research lab, Mr. Z trying to formulate a colloidal dispersion system with sodium lauryl sulphate. What type of colloidal system is suitable for sodium laurly sulphate and also we have to discuss the different stability factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it…

Jessica Vandeventer April 13, 2016 Energy Comparison of Fuels Purpose/Question- The Purpose of the lab is to see a comparison of fuels using a home made calorimeter. Hypothesis– The burner fuel is going to be a better source of fuel than the tea candle. Data Tables/ Graphs – Data Table 1. Mass and Density of Distilled Water. Mass of 10.0 mL of distilled water (g) Density of water (g/mL) 9.2g .92g/mL Data Table 2. Calorimetric Data. Fuel Source: Initial mass of fuel (g) Final mass of fuel (g)…

vertically and the number of drops being counted and recorded. Seven trials were done, with three chosen as the most precise (accurate to 4-5 drops). The pipette was then cleaned, placed back in test tube and excess hexanes disposed of into the hydrocarbon waste. Next a retort stand was set up with an iron ring attached with a watch glass placed on top about thirty centimetres from the lab bench. The watch glass was obtained from the fume hood, with tongs and was rinses with tap water and then…

Cholesterol and Fats By Name: Institution: Cholesterol has a sub-nuclear recipe of C27H45OH. This molecule is composed out of three ranges: a hydrocarbon tail, a ring structure District with four hydrocarbon rings and a hydroxyl total. The hydroxyl (OH) gregarious affair is polar, which makes it dissolvable in dihydrogen monoxide. This little 2-atom structure makes cholesterol an alcohol. The alcohol that we imbibe, ethanol, is a much more minuscule alcohol that moreover has a hydroxyl…

beneficial and essential process for oil companies. Fracking is a process of drilling and injecting fluid into ground at a high pressure to fracture shale rocks to release Hydrocarbons, but it has raised certain environmental concerns that that have burdened oil companies to overlook at the processes they are using to extract hydrocarbons. Certain concerns about Fracking are: Hydraulic fracking is quenching the water resources - 9.5 million gallons of water is used daily in places like Texas and…

different to elements and compounds because a mixture is made from molecules of elements and compounds that are simply mixed together, without chemical bonds. The combustion of metals is different to the combustion of hydrocarbon fuels because if you make a combustion reaction with hydrocarbon fuels, you create Co2 and particles of Carbon that are usually seen as soot or smoke. In the combustion of metals, you don’t create…

dioxide. Nitrogen dioxide forms from motor vehicles and other forms of combustion processes. Exposure to a lot of nitrogen dioxide can cause lung damage or respiratory diseases. The second pollutant is ozone. Ozone comes from exposure of nitrogen and hydrocarbons, which are emitted into the…
