Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)

Acid Strength Grade 10- Science (chemistry) 11/23/2012 Mariana Boff Acids Strength Acids are substances that contain hydrogen atoms which detach to form hydrogen ions when the acid is dissolved. Acids are divided into two main categories: the strong and weak acids. The stronger ones are very corrosive and can cause severe skin burns‚ here are some examples: nitric acid (HNO3)‚ hydrochloric acid (HCl) and sulfuric acid (H2SO4). The weaker ones are less corrosive and when in touch with the

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

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 of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although shop-bought vinegar usually measures 2.4 www.wisegeek.com/what-is-vinegar.htm fig 1 In this study we will determine the amount of acid in a vinegar

Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic

Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere
