ACID RAIN 1.) Define Acid Precipitation: Acid precipitation is a term used to describe any precipitation (rain, snow, fog) that has become acidic from reacting with compounds in the atmosphere. Acid precipitation forms when certain pollutants, most importantly sulfur dioxide and nitrogen oxides, combine with water in the atmosphere before falling to earth. Acid precipitation has a pH less than 5.6 which is the normal pH of rain. 2.)
1st hour 5/30/2010 [pic] Acid rain is the precipitation that falls to the Earth hundreds of miles away from where pollutant gases enter the atmosphere and has a pH of less than 5.6. Sulfur containing compounds are what cause acid rain, with sulfur dioxide being the most detrimental of the sulfur-containing compounds. The four common acids formed by the sulfur-containing compounds are sulfuric acid, SO3(g)+H2O(l)( H2SO4(aq), nitric and nitrous acids, 2NO2(g) + H2O(l) ( HNO3(aq) + HNO2(aq) and sulfurous acid, SO2(g)+H2O(l) ( H2SO3(aq). The sulfur dioxide (SO2) in coal is a major cause of acid rain. Since acid rain has very high emission rates, some attempts have been made to try to reduce the pollution from the rain.
It absorbs much water vapour from the oceans and land vegetation through evaporation. As this air rises it cools. Eventually the water vapour condenses into clouds and it then creates precipitation. So the equatorial region is both hot and wet. The air rises, then spreads horizontally to the north and south.
Indirect pollutants can be a lot of things, my main point is automobiles. The pollute the air by releasing unburnt fumes into the air. Beings there is so many vehicles on the roads today there is a lot of pollution. 2 The chemical with the lowest acceptable concentration is Aldrin and Dieldrin The chemical with the highest acceptable level of concentration is Chlorine 3 The water that come from our faucets comes from a well. It is softened by a water sofener and is then sent through Copper pipes to various outputs in my home.
Acid rain as a result of industrialization has had many negative effects on the New England region in particular. The Adirondack Mountains are of special interest due to their soil composition that does not allow for the seizure of the two primary particles in acid rain. This has caused issues pertaining to the water reservoirs in the area that now are sometimes unable to support life do to the high acidity. Acid deposition as it is more formally called is typically composed of sulfur dioxide and nitrogen oxide. These two components are naturally occurring from sources like volcanoes but the industrial revolution has exponentially increased the amount of these chemicals in the air.
Effects of haboob to aviation are that it causes wind smear, damages a plane’s engines, and affects landing and taking off among others. This paper aims to explore some of the negative effects haboob causes to aviation. Introduction Haboob refers to a dust storm that is common in regions that experience extreme drought conditions (Miller, 2010). These regions mainly include arid and semi arid areas. When it occurs, there is transportation of large quantities of dust particles or sand particles affecting transportation through limiting visibility.
When it rains, tiny raindrops are formed. The raindrops dissolve carbon dioxide gases in the air and form a weak carbonic acid. The raindrops then seep into the ground. The groundwater eats away at the calcite in the earth. Calcite is the main mineral in limestone rock.
What is acid rain? Acid rain is any form of precipitation with high levels of nitric or sulfuric acids. It can also come in the form of snow, fog, and tiny bits of dry material that settle to Earth. What effects does it have on plant material? It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees to take up water.
A device in the exhaust system of a motor vehicle, containing a catalyst for converting pollutant gases into less harmful ones. A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds. The three harmful compounds are: * Hydrocarbons (in the form of unburned gasoline) * Carbon monoxide (formed by the combustion of gasoline) * Nitrogen oxides (created when the heat in the engine forces nitrogen in the air to combine with oxygen) Carbon monoxide is a poison for any air-breathing animal. Nitrogen oxides lead to smog and acid rain, and hydrocarbons produce smog. In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe.
How carbon in the atmosphere is added to rocks and is gone back through the atmosphere? The movement of carbon between the atmosphere and the lithosphere (rocks) begins with rain. This is where atmospheric carbon combines with water to form a weak acid – carbonic acid – that falls to the surface in rain. The acid dissolves rocks – a process called chemical weathering – and releases calcium, magnesium, potassium, or sodium ions. The rivers then carry the ions on to the sea.
