One way we can make renewable resources is by the alcoholic fermentation of ethanol. Alcoholic fermentation is the process where yeast breaks down sugars into 2 pyruvic acid, and carbon dioxide and alcohol, or in this case ethanol. Ethanol is a main product in fuel, and it is a by-product from corn. Research Problem: In this experiment, we’re going to measure alcoholic fermentation by measuring the carbon dioxide bubbles that are produced per minute after forty minutes. Hypothesis: I believe that we should be able to get multiple bubbles of carbon dioxide, because the carbon dioxide is produced producing small air sacs.
Both are effective methods to release stored potential energy in an internal combustion engine and provide power to move a vehicle. Ethanol, generally E85, a mixture of 85% ethanol and 15% gasoline, is becoming more and more readily available at local gas stations and it is easily confused with normal gasoline at the pump. In fact, the United States government has a mandate in place that allows up to 10% of the fuel dispensed out of a standard gasoline pump to be ethanol. This would translate to an E10 fuel where undiluted gasoline would be E0. In terms of actual power content, “ethanol holds up to 76,100 BTU’s (19,025 Calories) of energy.
The burning of the fossil fuels is also the main contributor to global warming. Fortunately, alternative sources of energy that are environment friendly and also renewable are available to use. Biogas, an alternative source of energy, can be manufactured by humans by using human and animal waste. Windmills, Solar energy, Geothermal and Hydroelectric are all alternative and renewable sources of energy that are obtainable to in this modern era. This essay will be centred on how to harness those alternative sources of energy effectively.
It increases as the Earth’s atmosphere warms which makes it the most feedback mechanisms to the green house effect. Carbon Dioxide is released through natural activities like volcano eruptions and human activities like deforestation and burning of fossil fuels. We have seen that humans have increased their atmospheric CO2 concentration by a third since the Industrial Revolution. Methane is a hydrocarbon gas, which is produced through natural sources and human activities such as decomposition of wastes in landfills and rice cultivation. Methane is a more active green house gas than CO2 but is less abundant in the atmosphere.
Many of the products that are made from plastic contribute to many people’s lives. Without them, many of our products wouldn’t exist and make others more expensive. Even though plastics are the largest ingredients in our landfills, most of them can be recycled. It reduces the energy cost of making them from scratch again. They can also reduce carbon dioxide emissions.
Low density polyethylene (LDPE) – involves an older gas phase process (still used) with conditions: high pressure (1000-3000 times atmospheric), high temperature (300°C) and an initiator (an organic peroxide e.g. dibutyl peroxide, or oxygen). The resultant product has significant chain branching due to alkyl groups replacing hydrogen atoms on some carbon atoms. Consequently, the alkane chains cannot pack together in an orderly fashion, resulting in low densities and weak dispersion forces; therefore LDPE is soft, flexible and has a low melting point. The initiator isn’t strictly a catalyst as it is involved in the actual formation (one initiator molecule per ½ polymer molecule).
Oil is a fossil fuel supply which is not being created as fast as it is being drained. It is something that has been the cause of many deaths in two world wars. Hemp could be contributing to our independence in lieu of the government spending money to burn these crops that grow naturally. Some food crop production is being geared toward making a fuel called Ethanol. Ethanol is a healthy alternative to oil.
Now, it may not be a problem if we eat this occasionally, but the average person in the country consumes more than 20 teaspoons a day of high fructose corn syrup and the average teenager has 34 teaspoons a day. Over time, these heavy metals can accumulate in the body, causing health problems. Additionally, when we look at the chemical components of high fructose corn syrup on a spectrograph, we can see that it contains many weird chemicals that we know nothing about. That's why I say better safe than sorry. Look out for the red flag The main reason you should give up high fructose corn syrup is that it's a big red flag for very poor quality food.
These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
The Effects of Consumption on High Fructose Corn Syrup. High fructose corn syrup is a sweetener made by processing corn syrup to increase the level of fructose, usually to between 42% and 55% of the total sugar, with the balance being glucose. It is used extensively as a sweetener in processed foods and soft drinks, particularly soda and baked goods, but it is included also in many foods not normally thought of as sweet foods (“High”). High fructose corn syrup must be banned from all human consumption because of the negative health issues. High fructose corn syrup is associated with liver scarring.
