Photochemical smog is composed of many different compounds, but the three major ones are ozone, PAN and VOCs (Volatile Organic Compounds).
Ozone is written as O3 and is the product of the following reaction:
O+O2--->O3.
The singular O is formed when NO2 decomposes because of sunlight
PAN(peroxyacetylnitrate)is the product of VOCs oxygen and nitrogen oxide.
VOCs are uncombusted fuels, often the product of engines.

What is London-type smog?
The London type of smog (smog "Classic" as opposed to photochemical smog as is popular in other major cities) is the result of coal smoke (particulate matter from incomplete combustion and sulfur dioxide) and fog, The resultant heavy acidic mixture of smoke an dfog an create a number of problems related to acidic precipitation and health problems such as asthma.
Is smog an air pollutant?
Both the classic London smog (sulfur dioxide, fog and particulates) and the present photochemical smog (ozone, PAHs, hydrocarbon and nitrogen oxides oxides) are air pollution resulting from primary air emissions like hydrocarbons, sulfur dioxide, nitrogen oxides.
What are the harmful effects of photochemical smog?
It makes it hard to see and makes for bad horror movies.
What is the dirty haze that forms when pollution combines with moisture in the air?
Why, that would be Smog -- a worried derived from the two words, Smoke and Fog, first reportedly used in LA that has plenty of both.
Where does smog go?
Smog is released to the o zone layer.
Where else does smog occur besides London?
There hasn't been a smog in London for about 50 years.
What is London smog?
London-type smog is caused mainly by air pollution due to combustion of coal and emission of sulfur dioxide and dust. London smog has humid, foggy, stagnant air.
What is a simple explanation for smog?
smog was most recent in london so that is what we are learning
What capital is famous for their photochemical smog?
London
London-type smog results from the burning of?
coal
How did the great smog of London start?
It no longer exists/happens but in the days when London houses used coal fires to heat homes, the coal smoke mixed with normal fog to produce what was called "smog" (smoke and fog). It was very thick and very bad for health. London no longer has "smog" events because it no longer allows chimneys to emit smoke.
How much smog is in London?
thw pulltuion idsa me myself and i
What factors combined to cause the London smog in 1952?
My granddad :)
What is London Type Smog?
Smog is a layer of low level ozone, consisting of three oxygen atoms singly bonded together, it is formed from oxides of nitrogen and unburnt hydrocarbons, with the energy fro the reaction provided by sunlight.
What country is famous photochemical smog?
Photochemical smog can occur most anywhere. London-type smog comes from factories and the burning of coal and fossil fuels, where photochemical smog comes from hydrocarbons and nitrogen oxides mixing with sunlight.
What were two main causes of the extra deaths of the smog in London?
you tell me
Is smog a heterogeneous or homogeneous mixture?
Heterogenous. Not all smog is created equal. In New York City, for example,smog on the FDR drive during rush hour may have a different chemical composition from smog directly near the electrical generation plant ( more carbon, more perticulates etc.).
