The water that I placed activated carbon in actually increased by 2pH rather than decreasing. 3. Based on your data, what effect do you predict coal mining has on the environment? Answer = Coal mining is the removal of coal from the earth which slows the Earth's capability to decrease the acidity of groundwater. If an ideal pH level is 7 than the carbon was able to take our acidic water and make it more neutral.
It is very corrosive and causes severe burns. It is very harmful by skin contact or by inhalation of dust. This cocktail together is used for getting into the ground and then it contributes to global climate change creating air pollution. They argue that fracking harms the environment and can hurt other living species such as bird, and fish. All of this is true; however, natural gas is a cleaner burning fuel and it has other advantages.
al.). Some pollutants – for instance, polycyclic aromatic hydrocarbons – can lead to life-threatening diseases in humans and wildlife, such as cancer (Harvey). Scientists use many different methods to remove these pollutants from water supplies; one of those methods is the utilization of adsorption onto a porous substance, normally charcoal. Due to numerous circumstances, scientists have begun searching for alternatives to charcoal, one of them being Bentonite clay. However, Bentonite clay cannot be easily removed from the water, so in this project the students were instructed to modify the clay to make it magnetic and then compare its effectiveness in absorbing a model PAH against charcoal.
Ryan Agro Acid Rain Lab Purpose: I.V: Type of Stone D.V: Mass of rock after 5 days Control: Stone in Water Problem Statement: Acid rain causes some stones to loose mass. Which type of Stone is the best to prevent a loss in mass? Hypothesis: If the material used is affected by acid rain, then it will lose mass when exposed o vinegar, because of chemical changes. Procedure: 1. Gather Materials(container with lid, graduated cylinder, vinegar, balance, limestone, marble, red sandstone, granite) 2.
The ozone protects us from the majority of the harmful rays from the sun and it shields us from most of the sun’s heat. When we first found the oil sands they were covered with trees, shrubs and other plant life, to get to the oil we had to clear-cut. The clear-cutting destroys many habitats of animals. When an animal looses it’s habitat it either dies or it runs to the city, where it can be a potential threat. When we refine or even dig up oil sands we produce harmful chemicals.
Course # Student name / Names of members of group Date: Exp # : Estimating the effects of acid rain Introduction: Precipitation that measures a pH value below 5.6 is generally considered as acid rain. Burning fossil fuels is the main reason for the elevated levels of gaseous oxides in a polluted atmosphere that in-turn forms acid rain. Gaseous oxides such as that of carbon, sulfur, nitrogen and phosphorus could dissolve in water to form an acidic solution. A generalized reaction sequence on the formation of acid rain is as follows; One of the determinants of clean water in the natural environment is its alkalinity. Alkalinity can be defined as the capacity to neutralize acids.
The result was not just the super heated earth, it also resulted in oxygen depletion, the acid rain falling would have also been toxic with the ash and other debris in the upper atmosphere falling with it, this would have created an event of ocean acidification, killing many of the organisms that could survive the low oxygen levels in a normally pH balanced body of water. Many of the organisms and animals that did survive were small, and most could thrive if not survive in a low oxygen, acidic environment. “The collapse of marine ecosystems at the end of the Lopingian was most likely triggered by a sudden and widespread flooding over all relict shelves, following maximum emergence of epicontinental seas around Pangea” (Yin, Zhang, Shang). Many marine animals that survived could produce their own food, or lived off of the organisms mentioned above. But these animals never fully recovered, even after thousands of years they never reached the numbers that they once had.
Research question: Will the level of acidity of the rain have an effect on the corrosion of limestone, as measured by change in mass of marble chips in a beaker? Introduction: Acid rain is any form of precipitation due to excess or elevated levels of hydrogen ions. It is also a process by which acid particles leave the atmosphere. Natural rain has a pH of 5.6; this is due to the presence of carbonic acid by the mixture of carbon dioxide dissolved in water in the atmosphere. H2O + CO2 → H2CO3 The carbonic acid molecules immediately dissociate in water to form hydrogen carbonate ions: HCO3−, and hydronium ions, H3O+: H2CO3 + H2O → HCO3− + H3O+ The deposition of acid like sulfuric and sulfurous make rain water acidic this is from the sulfur
The chief advantage of hydro systems is it costs a lot less than other sources of energy. Hydroelectric plants are immune to price increases for fossil fuels and do not require imported fuel. On the other hand as hydroelectricity is increased petroleum/oil should be decreased. Hydroelectric plants generally have small to none emissions of carbon dioxide and methane due to reservoir emissions, and emit other pollutants associated with combustion. Hydroelectric plants may be able to reshape water flows to more closely match daily and seasonal system energy demands.
a. Pyrite hypothesis accept/reject = I would accept the hypothesis, seeing as how the pH reduced from 6 to 2. b. Coal hypothesis accept/reject = I would consider this hypothesis to be true as the pH increased from 6 to 10. 3. Based on your data, what effect do you predict coal mining has on the environment? Answer = Coal mining can require the removal of almost an entire layer of material deep under the surface.
