Environmental Science Dr Larsen 07/27/10 Air pollution Air pollution has been a problem for years and has caused many infections and depletion of the natural environment. The most recognized depletion is the depletion of the stratospheric ozone layer. Pollution has caused this and has been reason for the increase in human health problems. Indoor air pollution and urban air quality are listed as two of the world’s worst pollution problems in the 2008 Blacksmith Institute World’s Worst

9.1 Manufacture of Sulphuric Acid 1. State uses of sulphuric acid in daily life. - lead acid batteries in automobiles and for home use - extraction of elements from ores - manufacturing of fertilizers 2.The following shows an incomplete flow chart of the Contact process. a) b)Chemical equation A. B. C. D. 3. Briefly explain the sources of sulphuric dioxide gas in atmosphere. -Sulphur dioxide is produced mainly from the combustion of fossil fuels

Just imagine one day having to walk outside wearing a mask; or not being able to open the windows of your house on a hot summer’s day. Or even worse‚ imagine looking out of your window and not seeing any form of life. All vegetation has died due to acid rain and other chemicals such as sulphur poisoning. Some of these ideas can become a reality if something is not done about this problem‚ which‚ in my opinion‚ is far greater than the wars that are going on the world at this moment. There are two main

includes low birth weight‚ preterm delivery‚ and heart defects to the baby and there are almost 4.6 million people die each because of the air pollution. Along with harming human health‚ air pollution also causes several environmental effects such as acid rain‚ which damages forest and causes water bodies to be acidic‚ making these habitats unsuitable for fishes and other animals‚ as well as decaying the buildings‚ sculpture‚ and statues that are part of human property; ozone depletion‚ which increased

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

Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration of hydrogen ion is base. Base

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base‚ depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts‚ so it won’t change your experiments at all. It goes like this: 2H2O --> H2O + H+ + OH- --> H3O+ + OH- See how the hydrogen ion was transferred? Most of the

combustion etc. Due to air pollution‚ the composition of air is changing all over the world. Most of the gases and air pollutants are produced by burning fuels. Burning of coal produces carbon dioxide‚ sulphur dioxide etc. which are responsible for acid rain. Chlorofluorocarbons are widely used as propellants and as refrigerants which cause ozone depletion. Water pollution adversely changes the quality of water. It disturbs the balance of the ecosystem and causes health hazards. Water becomes polluted

Chandra Clark “Studies show that transportation sources such as cars‚ trucks‚ buses‚ ships and trains account for 90% of the cancer risk associated with air pollution” (europa.eu). Air pollution is the introduction into the atmosphere of chemicals‚ particulates‚ or biological materials that cause discomfort‚ disease‚ or death to humans‚ damage other living organisms such as food crops‚ or damage the natural environment or built environment. The Earth is surrounded by a blanket of air that’s polluted
