1a) Explain the classification of the selected energy resources shown. This resource shows the environmental impacts, social acceptability and economic costs of a select few energy sources. They are classified in this way for a number of reasons. Nuclear power is shown to have high economic costs, this is because it is very expensive to build and decommission nuclear power stations, it also an expensive process to mine, process and enrich uranium and plutonium required as nuclear fuel. Nuclear waste must also be stored for a very long period adding to the cost.
The unknown samples are strontium chloride and copper chloride. Some of the errors that might’ve occurred during our experiment could’ve been due to the fact that we didn’t have much time. Therefore, we rushed through the experiment and might’ve not washed the spatula properly before dipping it into a new substance. Due to this, the color of the flames emitted could vary and not be accurate because the different substances could’ve mixed. Lack of equipment could’ve been one of factors that contributed to our errors.
Secondly, there is excessive disposal, mainly caused by the geology, making many sites suitable for landfill. Landfill sites also produce gases including carbon dioxide and methane which contribute to global warming, making it very unsustainable. Toxic leachate may occur, which will inevitably harm animals and water courses. Although this is very unsustainable, the waste can be incinerated to produce energy (leading to less stress on other resources, therefore more sustainable), but there is concern on whether this acts as a carcinogen which can lead to the formation of cancerous tissues, still making it
Fracking is bad for the environment. People still need natural gas or oil to live their life. It will take time to get all of the bugs worked out of fracking. Fracking companies are using the new technology to insure the protection of the environment. Fracking is a cheaper way of obtaining gas.
In the end, chymosin took the shortest amount of time at 15 minutes to curdle and leaving us with the most curds. A possible error could have been at the start of the lab, where we exposed the test tube for too long. It could affect the results and outcomes because bacteria could have traveled inside when it was open for too long. It is possible that some of the curdling agents were taken in and out of our armpits too much, leaving us with inaccurate time. When it is taken in and out of our arms, it affects the heat, not allowing the product to get consistent heat temperature.
Coal is a cheap and, sometimes, free way to heat, but trailers are not properly equipped to heat with coal. Many of the trailers have a stovepipe sticking out from a window. Fires are common and fire trucks are not readily
People speculate endlessly about supernatural powers over pain and heat, or mysterious brain chemicals that block the pain and prevent burning. The simple explanation is that the capacity of light and fluffy coals to contain heat is very low, and the conductivity of heat from the light and fluffy coals to your feet is very poor. As long as you don't stand around on the coals, you will not get burned. (Think of a cake in a 450°F oven. The air, the cake, and the pan are all at 450°F, but only the metal pan will burn your hand.
Changing to alternative sources would be too expensive. Those that debate a change is needed say that Coal, oil and natural gas is polluting our atmosphere, the air that is breathed and killing wildlife. People will soon run out of these three sources and there should be a backup plan put into action before it is too late. I personally can see both sides; however, I want to see the United States use wind, solar or water for their energy sources. The United States is broke, and we owe so much money to other countries as it is.
All of this is true; however, natural gas is a cleaner burning fuel and it has other advantages. One reason fracking should be allowed is the jobs it creates. The fracking industry employs engineers, truck drivers, office administrators, construction workers, geologist, and well drillers, and the list is too large to include.
The usage of burning oil and coal can be costly. Most of these facts are hidden from us but it is true. Not only does it cost money to burn the oil and coal but the construction of these power plants, workers, materials, money for labor workers and the transportation of the substance. Sulfur dioxide is not environmental friendly and is probably one of the worst substances for our earth. It can cost billions of dollars to run a plant like this were recycling saves us tons of money on our renewable resources and has very little cost of reconstructing a product.
