Released Into The Atmosphere Sulfur Dioxide
1,318 wordsEvery thing present in this universe is a part of environment including ourselves. Whether they are animals, living thing, or nonliving things. All of the external factors affecting an organism. These factors may be other living organisms (biotic factors) or nonliving variables (abiotic factors), such as water, soil, climate, light, and oxygen. All interacting biotic and abiotic factors together make up an ecosystem. Organisms and their environment constantly interact, and both are changed by th...

Petri Dishes Test Tubes
899 wordsControlled Comparison: During class, our instructor set up the same lab that we were doing with 2 solutions, both of which were known acidic or basic. He placed 2 ml of the known acid into 2 different test tubes, and 2 ml of the known acid into 2 different petri dishes. Then using forceps, he tested blue litmus paper in one petri dish, and red litmus paper in another. The blue litmus paper, after being dipped into the solution, turned red in reaction to the acidic solution. While the red litmus ...

Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Effects Of Acid Rain Sulphur Dioxide
868 wordsThe damaging effects of acid rain on society is becoming overwhelmed with great amounts of pollution from cars, factories and an large amounts of garbage. The immense amounts of sulphur dioxide put into the air causes high levels of acid in the atmosphere. When this sulphuric acid is absorbed into moisture in the air, then rain can be harmful to the environment. Acid rain is destroying lots of things in our environment. It is hurting lakes, air and thew rest of our ecosystem. Acid rain is killin...

Copper In Nitric Acid
554 words3 Cu + 8 HNO 3 -- 3 Cu (NO 3) 2 + 2 NO + 4 H 2 O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. In this process the identifiable characteristics of the metal will be completely changed and a new substance, cupric nitrate, will be formed. Copper forms two series of chemical compounds: cuprous, and cupric. Cuprous compounds are easily oxidized to cupric, in many cases by simple exposure to air; cupric compounds are stable. When nit...

Effects Of Acid Rain Sulfur Dioxide
1,028 words"Acid Rain, " or more precisely acidic precipitation, is the term used to describe rainfall that has a pH level of less than 5. 6 -- a pH of 7 being neutral. This form of air pollution is currently a subject of great controversy because of the damage it does tot he environment and property worldwide. For the last ten years, this occurrence has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe. It also leads to the deterioration of buildings a...

000 Square Miles Acid Rain
1,060 wordsThe Adirondacks are a group of mountains surrounded by many lakes and rivers, that cover over 5, 000 square miles in the northeastern part of New York. There are a lot of large tourist villages on every lake. Motor boating and other water activities take place on almost every lake in the area. It is a vacation paradise for thousands. But, industrial emissions from Canada and the Ohio river valley always drift to this area and cause acid rain. This silent killer is destroying these beautiful lake...

Ph Of 5 Sulphur Dioxide
1,087 wordsAcidity is measured using a pH scale, with the number 7 being neutral. A substance with a pH value of less than 7 is acidic, while one of a value greater than 7 is basic. A substance with a pH of 6 is 10 times more acidic than another with a pH of 7. Usually the pH of 5. 6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5. 6 is the pH value of carbon dioxide in equilibrium with distilled ...

Sulfur Dioxide Acid Rain
318 wordsAcid Rain is, rain that is acidic (naturally). There is a pH level scale which tells if something is acidic or not. Due to certain chemicals in the rain it has a pH level of around 5. 0, and sometimes even 4. 0 (around volcanoes activity). The term acid rain is now used for rain with a pH below 5. Acid rain is caused when gases, generally like sulfur dioxide (SO 2), dissolves into water to form sulfuric acid. The rest comes from different oxides of nitrogen (mainly NO 2 and NO 3). The chemical r...

2 O 2 Bodies Of Water
1,333 wordsAcid rain pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO 2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or clou...

Clean Air Act H 2 O
1,801 wordsAcid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...

Western United States Sulfur Dioxide And Nitrogen
1,519 wordsAcid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries, coal burning factories, power plants and automobile engines are the main sou...

Absorbed Into Clouds Times As Acidic Acid
393 wordsAcid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone (SO'y, NOx, and O'y) is released into the air. These chemicals are absorbed into clouds and results in Acid Precipitation (Acid Rain, Acid Snow, Acid Hail, Acid Sleet). When the chemicals aren't absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entir...

Life On Earth B And C
1,459 wordsCarbon dioxide is a colorless, odorless, non-toxic, and slightly acid-tasting gas. Sometimes referred to as a carbonic acid gas, the molecule consists of one atom of carbon joined to two atoms of oxygen. It occurs naturally in the atmospheres of many planets, including that of earth. Carbon dioxide is uniformly distributed over the earths surface at a concentration of about 0. 033 %, or 330 parts per million. It was called fixed air by the Scottish chemist and physician Joseph Black in the 1750 ...
