  • Times A Day Burning Sensation
    1,998 words
    Millions of people around the world suffer from ulcers. An ulcer is a sore or hole in the lining of the stomach or duodenum (the first part of the small intestine). People of any age can get an ulcer and women are affected just as often as men. With stomach ulcers, H. pylori infection is found in 60 to 80 percent of the cases. Again, it is still uncertain how the infection acts to cause the ulcer. It probably weakens the protective mucous layer of the stomach. This allows acid to seep in and inj...

  • Clean Air Act Acid Rain
    1,807 words
    Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO 2) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. These compounds then fall to the earth in either dry form (such as gas and particles) or wet form (such as rain, snow, and fog). Prevailing winds transport the compounds, sometimes hundreds of miles, across state and national borders. Electric utility plants account for about...

    How Folate Can Help Prevent Birth Defects If you plan to have children some day, here's important information for the future mother-to-be: Think folate now. Folate is a B vitamin found in a variety of foods and added to many vitamin and mineral supplements as folic acid, a synthetic form of folate. Folate is needed both before and in the first weeks of pregnancy and can help reduce the risk of certain serious and common birth defects called neural tube defects, which affect the brain and spinal ...

  • Acetic Acid H 3
    842 words
    In the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

  • Effects Of Acid Rain Sulphur Dioxide
    868 words
    The 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...

The average annual cost for this phase is about one hundred and eighty five to two hundred and twenty dollars per ton. 7 To cut down on nitrogen oxide pollution, EPA will require power plants to reduce their nitrogen oxide releases, and will require reductions in nitrogen oxide releases from new cars. Reducing nitrogen oxide releases will reduce both acid rain and smog formation. Companies that rel...

  • Sulfur Dioxide And Nitrogen Burning Of Fossil Fuels
    1,264 words
    What is Acid Rain? Acid rain is a form of precipitation that falls to the earth as rain. For rain to be acidic it has a pH level of less than 5. 6. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, oil and other kinds of manufacturing. When these pollutants are in the air, they react with water and other chemicals, to form sulfuric...

    Acid Rain Written by: Ali Right Introduction Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5. 6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of...

  • Ph Of 5 Sulphur Dioxide
    1,087 words
    Acidity 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 ...

    Acid rain is a great problem in our world. It causes fish and plants to die in our waters. It also it causes harm to the human race, because we eat the fish, drink the water and eat the plants that have come in contact with this rain. It is a problem that we must all face together and try to get rid of. However acid rain, on it's own, isnt the biggest problem. It causes a larger problem such as aluminum poisoning, however, acid rain is very deadly, and the problems of it continuously surround us...

    Acid 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...

    How Acid Rain Develops, Spreads, and Destroys Acid rain is environmentally damaging rainfall that occurs after fossil fuels burn, releasing nitrogen and sulphur oxides into the atmosphere. Acid rain, simply stated, increases the acidity level of waterways because these nitrogen and sulphur oxides combine with the air? s normal rainfall. Acid rain is a silent threat because its effects, although slow, are cumulative. This analysis explains the cause, the distribution cycle, and the effects of aci...

    Acid RainA Contemporary World Problem Acid rain is one of the most dangerous and widespread forms of pollution. Sometimes called the unseen plague, acid rain can go undetected in an area for years. Technically, acid rain is rain that has a larger amount of acid in it than what is normal. The acidity of rain in parts of Europe and North America has dramatically increased over the past few decades. It is now common in many places for rain to be ten to seventy times more acid than unpolluted rain. ...
