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

Nitric Acid Nitric acid is an acid many people have come across in life. One may have felt nitric acid when touching fertilizers‚ or using dyes. Nitric acid appears in substances we never thing it would be used in. In fact‚ small contents of nitric is acid is found in raindrops that fall from the sky. Nitric acid‚ or known as NHO3aq is an acid formed from reaction of ammonia and oxygen. Nitric acid is a colourless acid when it’s pure‚ or can be found yellow or red. This acid can be very corrosive

Procedure: First‚ obtain a clean crucible‚ and heat it under a Bunsen burner until it is as hot as possible‚ about 15 minutes within a fume hood unit. The Bunsen burner will be used under the fume

-- Reactions with nitric acid These are more complicated. When most metals react with most acids‚ what they are actually doing is reducing hydrogen ions to hydrogen gas by adding electrons to the hydrogen ions. The metal is‚ of course‚ oxidised to positive metal ions because it loses electrons. But nitrate ions are also easily reduced to products like nitrogen monoxide and nitrogen dioxide. So metals reacting with nitric acid tend to give oxides of nitrogen rather than hydrogen

acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise the pH of the soil.The soil which is too acidic will be neutralised by the lime which is alkaline. H2O + CO2 -> H2CO3 2SO2 + H2O + O2 -> 2H2SO4

What are the consequences of cutting down trees? There are many consequences for the environment of cutting down trees. Known as deforestation it has huge effects on the environment. It one very big effect is the loss of biodiversity which is a direct effect of cutting down trees. There are many reasons of which humans act out deforestation. For example is so that we can set up cattle farms. Also grow crops of which can then be sold to people. Another reason is for urbanisation and for the building

travel by train or bus‚ they will spend more time on the way. Admittedly‚ with the popularity of cheap air travel‚ more consumption of fuel may lead to pollution of surroundings and degradation of air quality. Pollutants (e.g.‚ sulfur dioxide and nitric oxide) will damage our living circumstance. However‚ any transport tools have fuel consumption. The authorities have taken measures to alleviate this problem. To sum up‚ although there may be some fuel depletion‚ taking the clear benefits-- economical

Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops
