Carbon steel

in the chemical balance or chemistry of the Earth’s oceans due to the increased levels of carbon dioxide in the atmosphere caused by burning of fossil fuels (e.g. coal, fuel oil, and natural gas). Ocean acidification is distinct from global climate change; however, the global threats to ecosystems resulting from ocean acidification are theoretically similar as global warming and also, both are caused by carbon dioxide; therefore, several marine biologists have called ocean acidification as “the…

hypothesised that the longer the carbon chain of an alcohol the more energy output would be released and a longer flame length will be produced due to the extra carbon-carbon and carbon-hydrogen bonds. As the wick length increases so does the flame length and therefore more energy output will be produced. The data collected throughout the course of the three experiments partially supports the hypotheses. However, the results gathered when testing how the length of the carbon chain affects energy…

of coral reefs, would wipeout the foundation of most species in the tropics. The stress of bleaching and dying reefs could leach disease and toxins into the ocean. Atmospheric carbon dioxide and methane can lead to decrease in pH, making seawater more acidic and stressful for species of invertebrates and vertebrates. Carbon dioxide has an effect on calcium carbonate buffers in shallower…

In addition to the weakening of the ozone layer, carbon dioxide and methane gasses also play a role in increasing heat across the globe which results in climate change. Carbon and methane emissions heat up the earth and while the earth begins to heat up, polar ice caps begin to melt. The icecaps release furthermore methane gases into the atmosphere and continue to heat the globe. The melting of the icecaps also results in higher sea levels which in turn harm coral reefs and decrease the land of…

The purpose of this paper is to calculate the carbon footprint of my household. I also found an article of about a well-known person’s footprint to compare with my footprint. I must read the Affluenza by John De Graaf to have a better understanding of how the over consuming of the American People is destroying the environment. I need to figure out what I can do to reduce the carbon footprint in my household. I can do my part in contributing to a healthier planet. I need to be aware that global…

Where: i : Number of components Xi : Mole fraction for component ( i ) Cn: The total number of carbon atoms Cni : Number of carbon atoms for component ( i ) H_m = ∑ X_i H_mi (3.3) Where: Hm: The total number of hydrogen atoms Hmi : Number of hydrogen atoms for component ( i ) CnHm : The average chemical formula So the average chemical formula has been determined as in the above equations according to the percentages…

reagent from aryl or alkyl halides and demonstrate the principles of organometallic chemistry. The Grignard reagent was prepared via a radical mechanism. The Grignard reagent was then used to prepare a carboxylic acid from carbon dioxide, demonstrating its ability to create carbon-carbon bonds by acting as a strong nucleophile. As the R group of the Grignard reagent was unknown, molecular weight and melting point were then used to identify the resulting carboxylic acid. The molecular weight was…

Fatty acids and oil are organic substances, which are composed of carbon, oxygen and hydrogen. When carbon, oxygen and hydrogen are chemically combined with a carboxyl group, a long chain is formed, called as fatty acids. Alternatively, when fats react with water, they break into fatty acids and glycerin. Three chains of fatty acids when react with glycerol molecule, they combine to form triglycerides. Molecules of triglyceride are the basis of fats and oil. The difference in their chemical…

Is Perrier Bad for You? Perrier is carbonated bottled mineral water sourced from the Les Bouillens spring in Southern France. Although the water from the spring is already naturally carbonized, carbonic gas is added to it again as it is bottled. Because of the many health benefits this water promises, it became very popular among Americans who wanted to lead a healthy and active lifestyle. Perrier soon became a widely-used substitute for soft drinks or cocktails and has gained a reputation for…

Chapter-4 (Introduction to FEM Analysis using COMSOL MULTIPHYSICS) 4.1 Introduction: In simplest form we can define Micro Electro Mechanical Systems (MEMS) as miniaturized electro-mechanical devices made by using various techniques of micro-fabrication, where the dimensions can be in the range from less than one micron to several millimeters. Many MEMS devices are of the size of a grain or the eye of a needle. MEMS is indeed one of the most promising and emerging areas of engineering. This…
