Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining |Table 1: pH of Water Samples | |Water Sample |Initial pH |Final pH (24-48 hours) | |Pyrite |6 |6 | |Activated Carbon |6 |7 | |Water |6 |6 | POST LAB QUESTIONS Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? Pyrite hypothesis = I would guess ph would be lower. Coal hypothesis = I would guess ph would be higher. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this.
2. What effects might this steady increase of carbon dioxide have on the organisms living in this area? -As stated before, photosynthesis performers would not be effected, as the can take in carbon dioxide. Respiratory breathers, however, face a fatal issue with extra carbon dioxide in the air. The population of respiratory breathers will slowly decrease, considering plants will give a little bit of oxygen.
This requires the perfect information which is rarely even achieved. The government would find it hard to find the level of carbon emissions that is the correct amount. Some firms may not cut their emissions of pollutants if the fine they receive is less than the benefit they derive from polluting. Regulation of carbon emissions can also create a market for tradable permits. Other forms the government can use to correct market failure could include taxation, subsidies and information provision.
As well as when NaOH is in a solution form it absorbs carbon dioxide from the air which is weakly acidic. When the two mix, it partially neutralizes the solution. So the mass you take one day, will not be the same the next day. Lab 2: Standardizing NaOH Figure 1. This table shows the data collected while standardizing NaOH.
Along with other sustainable energy sources, nuclear power is a low carbon power generation method of producing electricity, with an analysis of the literature on its total life cycle emission intensity finding that it is similar to other renewable sources in a comparison of greenhouse gas(GHG) emissions per unit of energy generated. Besides that, with one uranium fuel pellet roughly the size of the tip of an adult’s little finger contains the same amount of energy as 17,000 cubic feet of natural gas, 1,780 pounds of coal or 149 gallons of oil. If we look at the use of land perspective, multi-reactor nuclear power plants like Palo Verde in Arizona with a single plant are able to produce electricity in quantities that would require over 60 square miles of photovoltaic panels, and from 15
In spite of this, if one compare this price to the amount of CO2 depleted by petrol and diesel vehicles , it gives the idea that if all classic cars would be supplanted with electric ones, CO2 emissions would be diminished by about 500 times. Despite the fact that Electric cars are moderately new at the mass production scale and are not yet answering many demands of improved expense, range and charging pace. Each of which will be aided by enhancing
CCS fitted plants experience reductions in overall efficiency by 8-30% because of ‘energy penalty’. Though consequentially, CCS plants could result in reduced CO2 emissions and improved environmental quality, the efficiency losses in the process leads to elevated use of fossil inputs which in turn results in more fuel extraction, need for more CO2 transport and storage, more particulate pollution (air and water) and landscape destruction and geo-engineering. Thus, there could be significant spin-off effects from an ethical perspective. For instance, need for more fuel extraction shall further reinforce the ethical contestations on the already notorious mining industry. Leakage (slow and abrupt) of CO2 during transport and storage besides posing health risks to humans and local flora and fauna may balance out the net effect of CCS on global warming.
In Ohaake in New Zealand about 320 gm of C02 is produced for each KW hour of electricity produced against 950 to 960 gm. if coal was used. Limitations Geothermal energy is a proven economical resource with energy technology. It has some environmental problems: 1. The steam brings hydrogen sulphide gas to the surface and pollutes the air unless controls are instituted.
Although this project is creating positive result, many people are still not sure of the value it would bring to Maldives. Some scientists have argued that just because there is carbon buried in the soil the nutrients will not stay there for any measurable amount of time. George Monbiot, a UK environmental commentator, stated that burying the carbon rich product in the soil will not at all
Filled with environmental consequences, hidden costs, and increased consumption, electric automobiles at this point in time do not benefit the environment. Electric automobiles are supposedly superior to traditional cars, but they still release the same amount of pollution during their production process. Since the only main difference between regular and electric cars is a bigger battery and lack of a combustion engine, mostly the same parts are manufactured in production. Factory emissions still make up a large percentage of our country’s release of greenhouse gases; therefore electric vehicles are still contributing to pollution. The chemicals involved in creating the metals and internal parts of the automobile also do not differ between electric and traditional automobiles.
