Acid Rain Within this past century‚ acidity of the air and acid rain have become recognized as one of the leading threats to our planet’s environment. No longer limited by geographic boundaries‚ acid causing emissions are causing problems all over the world. Some laws have been passed which limit the amount of pollutants that are released into the air‚ but tougher legislation must be implemented before this problem can be overcome. Acid rain is produced‚ when automobiles‚ smelters‚ power

1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA

Folic Acid is a B vitamin‚ specifically B9. It is an essential nutrient required by the body to create healthy new cells. While we hear about it mostly in regards to pregnancy‚ it is important to understand that the need for folic acid goes even beyond this. Folic acid is essential for the body to create red blood cells which in turn prevents anemia. It is also plays an important role in the metabolism of homocysteine‚ an amino acid. The recommended dietary allowance (RDA) for all men and women

also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the base. Preparation • Lab coats should be fully fastened

Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of

Acid Rain Air pollution is one of the most common outcomes of the combustion of fossil fuels. A common air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic acid derived
