What is difference between thermal and photochemical reaction?
Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)
What is the decomposition reaction caused by light called?
The decomposition reaction caused by light is called photolysis. This process involves the breaking down of a compound into simpler substances by absorbing light energy.
Is there two different types of smog?
Yes, there are two main types of smog: "photochemical smog" and "sulfurous smog." Photochemical smog forms in areas with a high concentration of automobile emissions, sunlight, and warm temperatures, while sulfurous smog is caused by the burning of coal and oil, emitting sulfur dioxide into the atmosphere.
What causes the tree sap to be purple?
Purple tree sap can be caused by a chemical reaction between the sap and certain minerals or compounds present in the tree. This reaction can create pigments that give the sap a purple color.
Would a false positive from the reaction between the inoculating loop and hydrogen peroxide be caused by poor specificity or poor sensitivity of the catalase test system?
The false positive from the reaction of hydrogen peroxide and the inoculating loop would be caused by poor specificity. The formula for specificity is TN/TN+FP.
What is the meaning of photochemical smog?
Photochemical Smog is any chemical reaction that takes place with the presence of sunlight. The most common example is Ground-level Ozone, caused by reactions of common pollutants along with their reaction to the sunlight.
What is difference between thermal and photochemical reaction?
Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)
Photochemical smog is caused by the action on chemicals of what?
Photochemical smog is caused by the action of sunlight on pollutants like nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the atmosphere. These pollutants react with sunlight to form ground-level ozone and other harmful compounds, creating the thick haze characteristic of photochemical smog.
Does photochemical smog is caused by the action of sunlight on chemicals?
yes, yes it does
What is the decomposition reaction caused by light called?
The decomposition reaction caused by light is called photolysis. This process involves the breaking down of a compound into simpler substances by absorbing light energy.
Photochemical smog is caused by?
Nitrous Oxide
Is a fossil fuel a photochemical smog?
Fossil fuels are coal,oil and natural gas. They are not themselves photochemical smog. That is a complex mixture caused by the action of sunlight on air containing substances released when fuels burn. Thus it is connected to fossil fuels, but it is not the same thing.
How does photochemical smog differ from industrial smog?
London-type smog is caused mainly by air pollution due to combustion of coal and emission of sulphur dioxide and dust. Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances.
Why did the Olympic pool turn green?
The Olympic pool turned green due to a chemical reaction between chlorine and organic compounds in the water, caused by sunlight and algae growth.
What are the cause of smog of acid rain?
it is caused bye photochemical smog and acid rain
What are problems caused by photochemical smog?
Problems caused by photochemical smog are:It will cause a decrease in lung capacity and lung elasticity.It will cause damage to leaf tissues.It will corrode synthetic material.It will crack rubber and synthetic rubber products.
What are the measures to control smog?
Photochemical smog is caused by the mixing of hydrocarbons and NOx in the presence of sunlight. Smog may be controlled by: * Controlling industrial emissions of the precursors * Reducing automobile emissions by reducing traffic or increasing pollution control
