How Does Carbon Compound In Alcohol Affect The Combustion Of Alcohol

Many combustion reactions involve the burning of organic compounds called hydrocarbons, compounds containing the elements carbon and hydrogen, or other organic compounds. When a hydrocarbon is burned completely, the products of the combustion reaction are usually carbon dioxide and water. Natural gas, propane, and wood all burn to produce carbon dioxide and water as the products.

From the data analysed, a clear trend is seen. As the amount of carbon chains (and consequently molar mass) increases, so does the heat of combustion released. The hypothesis was stated as: “because 1-hexanol has more carbon bonds, it will produce the most amount of heat in the shortest period of time. By following the same reasoning, it is suggested that 1-hexanol will be followed by 1-pentanol and 1-butanol, respectively.” The experimental values show there is a linear relationship between the carbon chains and molecular weight, and the heat of combustion

For instance, pentan-1-ol, the alcohol utilised to synthesis 1-pentyl ethanoate, is relatively flammable due to the hydroxyl functional group attached to the molecule. Therefore, in order to prevent severe burns, a laboratory coat and safety glasses were worn. The experiment was additionally performed whilst standing up, so that if the aliquot of pentan-1-ol ignited,

Different alcohols (methanol, ethanol, and 1-propanol) will all be used within their respective spirit burners.

Generally ethanol is an alcohol found in alcoholic drinks. At 100% concentration, it is pure and a colourless liquid with a strong odour (due to weak Van der Wall forces :D. Ethanol is produced by the fermentation of carbohydrates in yeast cells and is used frequently as a solvent.

According to Oxford Dictionaries, alcohol is a colorless volatile flammable liquid that is produced by the natural fermentation of sugars and is the intoxicating constituent of wine, beer, spirits, and other drinks, and is also used as an industrial solvent and as fuel (Fowler, H. W., Fowler, F. G., & Murray, J. A. (1964). The concise Oxford dictionary f

According to the graph in figure 5, as the number of Carbon atoms in alcohol increased by 1, the change in standard enthalpy of combustion would increase by around 200 kJ/mol. This is proven as the equation of the linear line (protruding from the bottom left to the top right of the graph) is y=199.81x, where x is the number of Carbon atoms, y is the standard enthalpy of combustion and 199.81 is the gradient of the line and how much the standard enthalpy of combustion would increase by when multiplied by x. There were also errors/uncertainties that were shown in the graph and result tables. The average error of each of the different alcohols was of 6.51%. Thus, as the change in standard enthalpy of combustion of the alcohols increased, the uncertainties and errors became greater. The size of the uncertainties can be seen becoming greater as the size of the change in standard enthalpy of combustion increases in the graph of figure 5 and the results table of figure

Many people assume alcohol is nothing more than liquor or rubbing alcohol; however, this is not the case. There are many different types of alcohol including some of the alternate fuels we put into our vehicles. Over the course of my working life I have come into contact with many different alcohols, but Isopropyl Alcohol, or 2-propanol, was one of the ones that I encountered the most and I have always wondered exactly what it is. 2-propanol is a very interesting molecule and has a lot of uses for products in many different markets. Because of this, many people come into contact with it and do not even know it. There are many important advances going on with the development of isopropanol that could potentially change our lives. Although, it is important to know and understand the products that you are coming into contact with because some of them might be

This graph on the other hand, shows a pattern between the scales of carbon lengths in molecules. The higher amount of carbon in a longer chain, results in a higher molar heat of combustion. This supports the theory behind bond energy as more bonds break, more bonds form which add up to making a higher molar heat of combustion.

In Whiting S. Albert’s article “Alcohol Use Is Harmful” he stated that alcohol is a chemical that contains hydrogen and carbon. Whiting stated further that the active ingredient of alcohol is ethyl alcohol, which is also known as ethanol. Alcohol is one of the few things that human being consume that do not need digestion. Alcohol appears the bloodstream immediately, thus, its intoxicating effects are felt instantly (1). “High levels of mortality, morbidity, and social malaise are associated with abuse of alcohol, and increasing numbers of women and youth are abusing alcohol” (Ferreira and Darryn 1). “Alcohol slows down the function of all living cells, especially those in the brain” (Whiting 1), which causes thinking to be impaired. Alcohol is probably the most used drug worldwide. “Three in ten adults 18 years of age and over have had alcoholism and/or engaged in alcohol abuse at some point in their lives …” (“Impact of Alcoholism” 1). According to Centers for Disease Control and Prevention,

The chemical formula of ethanol is made up of 2 carbons, 6 hydrogens and 1 oxygen and is classed as an alcohol (Material safety data sheet, 2001). Ethanol has a boiling point of 78.5c, density of .789 and a molecular weight of 46.0684mol (Biofuels Association of Australia, 2015). Ethanol is now usually used as a fuel for vehicles in its pure form as a replacement for gasoline, where it is blended with gasoline to improve vehicle emissions and power (Biofuels Association of Australia, 2015).

As we all know, alcohol is a product that has provided a variety of functions for people in the world. Alcoholic beverages have been consumed by humans in the very early time, they were one of the most popular drink and have been widely used in everywhere of the world. Also they were used medicinally, chemically, physically and so on.

The production and consumption of alcohol occurs in most cultures of the world, from hunter-gatherer peoples to nation-states.[2][3] Alcoholic beverages
