Sulfuric acid

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

salicylic acid into a form that would provide the same medical benefits without the side effects. In 1852, Charles Gerhart was the first to attempt to acetylate the hydroxyl group thus creating acetylsalicylic acid. However the acetylsalicylic acid product…

1. Pyrimidines are heterocyclic aromatic amines which, together with purines, form nucleotides. Nucleotides are the building blocks of nucleic acids, the basic structural component of DNA and RNA. The pyrimidines in DNA are cytosine and thymine, and in RNA uracil replaces thymine (Bettelheim, Brown, Campbell, Farrell & Torres, 2013). 
DNA and RNA are found in the nuclei of all cells and their job is to transmit the information needed for cellular growth and reproduction (Averill & Eldredge,…

Introduction The objectives in this laboratory were to explore the titrations of several known acids and bases as well as observing the mole reactions of the chemical reactions that each compound undertook. The four following acids and bases were used to predict when a set amount of reactant would reach equilibrium: Hydrochloric Acid (HCl), H2SO4 (Sulfuric Acid), NaOH (Sodium Hydroxide), and Ba(OH)2 (Barium hydroxide). An unbalanced equation of each reaction was given so the balanced equation…

Our Air is something we take for granted as opposed to food or water we don’t really contemplate much about it. Similar to the way we breathe it’s just a part of our life whether we consciously think about it or not. Comparable to our subconscious breathing is the autonomous effects polluted air can have on just about every aspect of the world. Its indisputable to say all of you know in our lifetime, environmental concerns revolving around our expenditure of fossil fuels and the effects it has…

Acid Rain Controversy The acid rain problem that everyone faces today demonstrates one thing in particular, and that is, finding new means and approaches that will enable us to defend and protect ourselves, as well as the environment, from the continuous destruction and devastation caused by acid rain. Acid is no longer just an aberration that resulted from the choice of civilization (Yadav, 2012). Everyone can no longer deny the fact that the effects of acid rain had become more than what the…

the remaining catalase into a new medicine cup and heat it in the microwave. Repeat the above procedure 3 times using the heated enzyme to dip circles into and record data. Finally take the rest of the original catalase and add a drop of hydrochloric acid to it. Repeat the above procedure 3 times using the acidified enzyme to dip the circles into and record data. b) Take a test tube and place a…

Specifically, nitration plays an important role in regulation of key enzyme activities and signal transduction networks. Tyrosine is one of the 21 amino acids and is important in the synthesis of certain hormones. Nitration of tyrosine can affect protein function, which can in turn link nitroxidative stress to alterations of molecules present in disease (Peluffo et al. 2007). Potential activation of proteins…

The major bottleneck for lipid extraction from the wet microalgae is the low extraction efficiency, because of the immiscibility of nonpolar organic solvents with water contained in wet microalgae {Yoo, 2012 #31} {Kim, 2013 #118}. Traditional method for lipid extraction from dry biomass uses a co-solvent system, which consist of a non-polar solvent and polar solvent {Halim, 2012 #7} {Kim, 2013 #118}. When the co-solvent system is directly applied to wet microalgal biomass, the microalgal cells…
