formation of photochemical smog

When pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight, smog is formed. This is a mixture of gases and since it is formed by photochemical reactions, it is called the photochemical smog. The word 'smog' is derived..

Photochemical smog occurs due to the action of sunlight on air pollutants, generating photochemical reactions. The principal constituents of the photochemical smog are gaseous hydrocarbons (leading to ozone formation) and oxides of nitrog..

Smog is mixture of smoke and fog containing particulates. Two types of smog exist, classical or original smog and the more recent photochemical smog..

>Some of the effects of air pollution are: Global warming- due to which temperatures are going up every year. Formation of photochemical smog formed when pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight. It hampers visibility and cau..

Coal is mainly elemental carbon with small amounts of hydrogen, oxygen, sulphur and nitrogen. On complete combustion of coal, carbon dioxide is the main product formed. This is non-toxic, but contributes to the green house effect if produced in excess. Small amounts of oxides of nitrogen and oxide..

Air pollution can be controlled by different methods depending on the source and the pollutant. The different methods are: One of the major causes of air pollution are the automobiles. The fuels being used should be lead-free as this will reduce the level of lead in the atmosphere. The carburetor s..

Vapours of any acid introduced into the atmosphere causes acid mist. 'Sulphuric acid mist' is produced when SO 3 present in the atmosphere, comes in contact with moisture. Sulfur trioxide (SO 3 ) is produced by complete combustion and forms sulfuric acid by the mechanism below:..
