what is the difference between industrial and photochemical smog?
14088
Industrial smog comes from, clearly, industrial processes. It concentrates in urban areas and is formed from sulfur dioxide (mostly from burning coal), water droplets, and other particles such as dust. Photochemical smog is a mixture of all other pollutants, but mostly VOC's and nitrous oxides.

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.

Photochemical smog (brown smog) is formed by the reaction of nitrogen oxides and VOCs with tropospheric ozone. ... Sunlight breaks a bond and releases one oxygen forming nitrogen oxide (NO). The lone oxygen then bonds to atmospheric oxygen (O2) with the assistance of sunlight. This forms tropospheric ozone (O3).

Here is a gross simplification from my perspective only. Industrial Biochemistry is the development and isolation of proteins and enzymes from natural and / or recombinant sources. ... Industrial Chemistry is usually involved in the manufacture of Organic and Inorganic compounds on a larger scale.

There are many types of primary pollutants, including carbon oxides, nitrogen oxides, sulfur oxides, particulates, lead, and volatile organic compounds. Secondary pollutants form from chemical reactions that occur when pollution is exposed to sunlight.

The oxidised hydrocarbons and ozone in the presence of humidity cause photochemical smog. Hydrocabons +O2,NO2,NO,O3→ peroxide , formaldehyde, peroxyacetylnitrate (PAN) ,acrolein etc.

The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.

Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm).

Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. ... When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.

The main difference between the two processes is that in the photoelectric effect, the electrons are emitted to the space whereas, in photovoltaic effect, the emitted electrons directly enter a new material.

The best way to control smog is to avoid the release of NO2 and hydrocarbon vapours in atmosphere. ... Scientists have developed automotive pollution control device that check the emission of NO2 and hydrocarbon vapours in the atmosphere. That device is a gift of green chemistry to control the photochemical smog.

Distinguish between classical smog and photochemical smog. ... Classical smog is a mixture of sulfur dioxide and coal smoke with fog. Photo chemical smoke is a precipitate in the reaction of the nitrogen oxide and other chemical compounds in Sunlight.

Smog differs in the properties with smoke and fog as well. Classical smog is a mixture of sulfur dioxide and coal smoke with fog. Photo chemical smoke is a precipitate in the reaction of the nitrogen oxide and other chemical compounds in Sunlight.

What is the difference between bleach and Clorox? ... “Bleach' is not some specific chemical. Chlorox is the brand name of a particular blend of bleaching chemicals and additives. Bleaching agents are oxidizing chemicals.

- Photochemical smog forms when large quantities of hydrocarbons and nitrogen oxides emitted, mainly from moto vehicles, into the troposphere under the influence of sunlight. - It occurs in cities where there are large numbers of vehicles, sunny days, and conditions.

The environmental case LPG is particularly clean-burning and produces fewer particulates – no big clouds of black smoke are emitted from our exhaust, as so often happens to older diesel cars. LPG cars produce 50% fewer nitrogen oxides than petrol, and 20 times fewer than diesel.
