Oxidation occur s when a substance poses an electron and combines with another substance. In some cases this reaction is initiated by having the atoms excited by a wave lenght of light such as the Ultraviolet. Thae presence of a catalystic surface like TiO may assist the process.
Photochemical oxidation is therefor the reaction of a chemicla cjhange in a substance which causes it to lose electrons which is initiated by light.
A common example is photochemical smog which is caused by hydrocarbons and NOx reacting under the influence of UV light
What else can I help you with?
Oxygen in air causes iron to rust so iron and oxygen are what in this process?
In this process, iron is the reactant undergoing oxidation, while oxygen is the reactant driving the oxidation reaction that causes iron to rust.
What is the process of burning something?
This process is called cellular respiration and is an oxidation.
Which does NOT involve an oxidation process?
Photosynthesis does not involve an oxidation process. Instead, it is a metabolic process in plants where they use sunlight to convert carbon dioxide and water into glucose and oxygen.
What cellular process releases energy from food?
oxidation
Give two definitions of oxidation?
Oxidation is a chemical reaction in which a substance loses electrons, resulting in an increase in oxidation state. Oxidation can also refer to the process of combining a substance with oxygen, leading to a chemical change.
Can oxidation stop the rotting process?
Actually, oxidation is a part of the rotting process.
How does lemon preserves food?
The acidity slows down the process of oxidation The acidity slows down the process of oxidation The acidity slows down the process of oxidation
What is removed in oxidation?
Oxidation is the process of adding oxygen or taking away hydrogen.
What is the process rusting called?
Oxidation
Is rust a process?
No, it is the result of a process scientifically known as oxidation.
Oxygen in air causes iron to rust so iron and oxygen are what in this process?
In this process, iron is the reactant undergoing oxidation, while oxygen is the reactant driving the oxidation reaction that causes iron to rust.
What is the process of burning something?

What is the final oxidation numbers of gold and zinc after the cyanide process?
the oxidation number is from 0 to 3+
a process Which involves gain of oxygen or loss of hydrogen?
Oxidation is a process that involves the gain of oxygen or the loss of hydrogen. During oxidation, a substance loses electrons, resulting in an increase in its oxidation state. This process is commonly associated with the formation of oxides and release of energy.
When an element is oxidized what does its oxidation number do?
When an element is oxidized, its oxidation number increases. Oxidation involves the loss of electrons, so the oxidation number becomes more positive in the process.
