ACID RAIN Cantarelli‚ Ilaria García Díaz‚ Bianca Gressier‚ Emilie Martínez Rivas‚ Carmen What’s the acid rain? Acid rain is a rain or any other form of precipitaton that is unusually acidic. What causes acid rain? Acid rain is caused by the burning of fossil fuels. Burning oil‚ gas and coal in power statons releases Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere. These gases mix with water droplets in the atmosphere creatng

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

Title: Experiment 17‚ Reaction kinetics – Determination of the activation energy of the reaction between oxalic acid and potassium permanganate. Objective: To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Introduction: Chemical kinetics is the study of chemical reaction rates‚ how reaction rates are controlled and the pathway or mechanism by which a reaction proceeds from its reactants to its products. Reaction rates vary from the very fast‚ which

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

makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can be transformed to products at the rate of thousands of times per second with the enzymes. If we consider the total

structures and properties of amino acids know the groups of amino acid What are amino acids? Amino acids are molecules that when combined with each other proteins. Amino acids contain a central tetrahedral carbon atom (α-carbon) amine group‚ carboxyl group‚ R-side chain The R-side chain determines the different amino acids There are 20 common amino acids Amino acids can join via peptide bonds Several amino acids occur only rarely in proteins Some amino acids are not found in proteins 3D

Title: Stoichiometry Reaction Objectives: 1. To decompose sodium hydrogen carbonate (sodium bicarbonate) by heating. 2. To accurately measure the degree of completion of the reaction by analysing the solid sodium carbonate product. 3. To calculate amount of product with given amount of reactant. 4. To determine amount of heat release in the reaction. Results: Part 1: Thermal Decomposition of NaHCO3 Materials Mass (g) Clean and dry test tube 15.1632 Clean test tube + NaHCO3 17.1647

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

The intent of this paper is to educate individuals about acid rain‚ define its chemical makeup‚ and describe its impact on the environment. Rain is an important part of all life; it is the source of water for almost everything. In some areas rain is actually a threat to life because of pollution from cars‚ factories‚ and power plants. This pollution releases gases into the atmosphere to create acid rain. Acid rain is rain‚ or any other form of precipitation that is uncharacteristically acidic

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
