What are the chemical reactions between combustible materials and the oxygen contained in atmospheric air?
The oxidation of combustible materials is called burning, or fire.Other forms of oxidation include rust and tarnish, which occur to materials that do not normally burn. Oxidation as a change in chemical state is called reduction, or redox.
What is true about oxidation-reduction reactions?
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
What is the oxidation state of oxygen in H2O2?
O = -2 oxidation state H = +1 oxidation state
What is the oxidation of SO2?
S = +4 oxidation state O = -2 oxidation state
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.
How does the oxidation state of 0 change in the following reaction?
The oxidation state of an element with oxidation state 0 cannot change, as it already has a balance of electrons.
What is the name of K- oxidation state?
-1 oxidation state. This ion should be called Kallide

Did cl change oxidation number tue or false?
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
Are all reactions that form compounds from elements a redox reaction?
Yes, because an element is in oxidation state ZERO. A reaction is redox only when there is a change in oxidation state of relevant species. So if a compound is formed from elements (as opposed to other compounds) there by definition has to be a change in oxidation state.
Why lose of electrons is called oxidation?
The loss of electrons is called oxidation because it involves the increase in oxidation state of an atom or molecule. Oxidation is characterized by the loss of electrons from a substance, leading to an increase in positive charge or a decrease in negative charge.
What is true about oxidation-reduction reactions?
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
What is the change in the oxidation number of Cr?
The change in oxidation number of Cr depends on the specific reaction or compound involved. For example, in the reaction from Cr(III) to Cr(VI), the oxidation number of Cr changes from +3 to +6, indicating an increase in oxidation state.
Is the chemical change that occurs when flues are burned is called oxidation?
Yes, it is.
Oxidation state of chloride?
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
What is Ca element to its oxidation state.?
The oxidation state of calcium is +2.
What is carbons oxidation state of methanol?
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
