The task the town council requested was to determine which of the three materials limestone, granite, or red sandstone was better for statues at the local zoo. To establish the most useful material, test how much the pH of the vinegar changed after the rock reacted. The stone which will be the most effective is the one which reacted with the acid rain the least. The greater the pH change the higher the reaction was. Consequently the material with the lowest pH difference would be the most reliable. Neutralization is when acids and bases change into salt and water. The reason this is important to the lab is if the material is more of a base there will be faster deterioration of the material. Acid rain is rain that is highly acidic due to atmospheric pollution. The pH value of acid rain is 4.0. Results of acid rain can be severe causing the death of plants and animals. It will also harm statues and buildings. The Statue of Liberty used to be copper, but due to the effect of acid rain over time it has turned green. When compounds such as sulfur dioxide and nitrogen oxides are released into the atmosphere, they mix and then react with water, oxygen, and other chemicals. Once these chemicals combine in the air acid rain is created. The geocycles which are involved with acid rain include the sulfur cycle, nitrogen cycle, and the water cycle. The sulfur …show more content…

If the stone was left in the vinegar for a longer period of time, then the pH level of the vinegar would have a greater change. Because it has had more time to react with the stone. Yes the hypothesis was supported, we tested the pH of the vinegar in the beginning and it was 2. After 10 minutes of vinegar with limestone the pH changed to 3. The material which was affected most by the acid rain was the limestone. Reasoning behind this is, the pH changed the most out of all three

DeekshithKumar Thadishetti Professor mankerian LS 690 July 31 2015 Climate change is one of the global issue that requires multiperspective approach. One of the key cause of climate change is air pollution. Air pollution occurs as a result of release of greenhouse gases to the atmosphere. There are two key sources of air pollution that should be targeted if the air pollution is to be reduced. The first source is the industrial stationay sources, which include electric power facilities.

My aim is to determine the effects that low pH levels have on the growth of cyanobacteria and algal species, by testing various concentrations of sulphuric acid (H2SO4) in different samples of cyanobacteria and algae of equal volume. My hypothesis is that the lower the pH level of the water, the less the cyanobacteria and algae species will grow. Thus the higher quantities of sulphuric acid in the water will result in the lowest growth rate of the cyanobacteria and algae species. Various chemicals have been released into the air, changing the mixture of gases in our atmosphere, hence resulting in a dramatic increase of acid rain levels.

Sulphur dioxide, nitrogen oxides, and sulphuric acids are the main cause of acid rain and urban smog. Acid rains are caused by these chemical compounds released into the air, which reacts with water and oxygen high up in the atmosphere and falls down as a more acidic pollutant known as acid rain. Acid rains dissolve limestones (that are used in statues and building) and can also travel a long distance which would also harm other cities. Urban smog is a yellowish or blackish fog formed by pollutants in the air trapped by layers of air with the different temperatures that prevent air from floating up.

Tracking Down Acid Rain and Precipitation Acid Rain with types of precipitation involves a high levels of Sulfur and Nitrogen. One way it can be created is by the vehicle's interior combustion. The smoke exiting the from the back part vehicles exhaust is nitric, and the sulfur is fossil fuel combustion and found in rock and minerals. If they both mix with each other is will leads to toxins air.

Annotated Bibliography Smol, John P. “Climate Change: A planet in flux.” Nature.2012 Supplement, pS12-S15 Human activities are affecting the earth’s climate, the world’s carbon dioxide is increasing by about 60 billion tons a year, which is the cause of global warming gasses. In this article, John focuses on the effects of global warming on animals, plants and human agricultural activities. If you plan to write an article about the global warming, John’s article would be a good starting point. Of course, this article also told us that global warming is a very urgent problem, it requires cooperation between countries to cope jointly.

1. List some sources of acid rain. Acid rain is made by a chemical reaction that starts with sulfur dioxide and nitrogen oxides which is the main cause for the harmful effects of acid rain released in the air. These compounds get into the atmosphere where they get mixed and start to react with oxygen, water and other different chemicals to make acid rain. Sulfur dioxide and nitrogen oxide both can dissolve in water.

The purpose of this assignment lab was for us to determine if there has been a decrease or increase in carbon dioxide emission in the data we were given in the past forty years. I have observed the data collected in five different locations around the world. The locations I have observed were in Summit Greenland, Hawaii, American Samoa, Alaska and the South Pole. Each one of the location was verified by its location code and the level of carbon dioxide within the years observed.

I did not expect for the plants to actually absorb the acidity from the water and become acidic itself. My research was confirmed that the plant would break down and die because about two weeks with the plant sample in vinegar the leaves lost their opacity and color. The lab results involving the vinegar as ocean water substitute was pretty accurate to all the research that I found about calcium carbonate animals and ocean plants. Ultimately both broke down in their own ways and the acidity wore down the samples very quickly.

In this article, Gardiner goes over the treaty that was proposed called the United Nations Framework Convention of Climate Change of 1992. This treaty addressed the world problem of climate change that’s causing global warming that would pose a significant threat to the world in the future. Several countries were offered to participate in this treaty, and many developed countries signed, but the United States government chose not to. The fact that the U.S. chose not to sign led the population to have many ethical questions about the topic and whether climate change actually did pose a significant threat. Gardiner argues that there are “five concerns of climate policy.”

This will cause acid rain to fall to the ground. Last of all, according to EPA, normal purify drinking water is at a pH level of 7, and normal rainwater is at a pH level of 5.6l. On the other hand, acid rain has a pH level of 4.2 to 4.4. The sulfur dioxides and nitrogen oxides will combine with clouds in the atmosphere, which it will cause acid rain. In short, the sulfur dioxides and nitrogen oxides will combine with clouds to fall from the sky, which has a pH level of 4.2 to

Some people call it acid deposition because they say it is a more precise name due to the fact that acid rain isn’t only rain, it can fall as rain, snow, sleet, hail and anything else. Acid rain has been formed because as we release harmful gases into the atmosphere, we are lowering the pH of precipitation, creating acid rain. Acid rain can kill small organisms such as trees and fish which destroys ecosystems. Although acid rain is not known to affect humans immensely, it can however, cause health issues usually lung

Climate change can be the main factor in the increase of extreme weather events around the world, researchers say that climate change will increase the frequency of these kind of natural disasters including heavy rainstorms and floods, putting many nations in the danger of devastation. Floods that used to happen one in a century now it happens four or five times during that same period, causes huge lost in homes and lives. Some small floods may not have large affects on the areas they happen in, but those little damages should not be ignored nor underestimated because one thing leads to another, the increasing of those little events associated with climate change put the society at risk of unknown challenges. This report will look at some…
