Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually

Experiment # 1 Date: 18/12/13 Title: Chemical Properties of Alkanes. Aim: To test the reactivity of alkanes using cyclohexane as an example. Apparatus/Materials: Cyclohexane‚ liquid alkane‚ aqueous bromine‚ test tubes‚ light source‚ watch glass‚ splint‚ 0.1 MKMnO4‚ concentrated H2SO4‚ dilute H2SO4. Method: Combustion: 1. A watch glass was placed on a benched protection sheet in a fume cupboard and the extractor in the fume on. 2. 4 drops of cyclohexane was placed on the watch glass using

Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work

Nutmeg to Trimyrisitin to Sodium Myristate to Myrisitic Acid Mandy Boyle Chem 213‚ Section 002 Due Date: December 3‚ 2009 I. Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols. Companies such

intermolecular forces between solvent and solute molecules. For example‚ in aqueous solvents‚ the polar solute can interact with the solvent via hydrogen bonding‚ electrostatic forces‚ ion dipole forces‚ dipole-dipole forces and London forces. All of these can help a polar solute dissolve in an aqueous solvent. Polar molecules can be involved in these interactions because they have a partial charge. This partial charge is brought upon by the differences in electronegativity between the atoms in the molecule

Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

Abstract The aim of this experiment was to determine which of the samples of vinegar if any had been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production

Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte
