The change in the oxidation number of Mn is?
The change in oxidation number of Mn in a reaction is determined by the difference in oxidation numbers before and after the reaction. For example, in the reaction MnO2 → Mn2O3, the oxidation number changes from +4 to +3, resulting in a decrease of 1.
Rusting of iron is an example of?
Rusting of iron is an example of a chemical reaction known as oxidation, where iron reacts with oxygen in the presence of water to form iron oxide (rust). It is a slow process that weakens the iron over time, eventually leading to its deterioration if left unchecked. Rusting can be prevented by using protective coatings or by controlling the environment to limit exposure to water and oxygen.
What is a redox reaction Give an example?
A redox (oxidation-reduction) reaction involves the transfer of electrons between reactants. For example, the reaction between iron (Fe) and oxygen (O2) to form iron oxide (Fe2O3) is a redox reaction. In this reaction, iron atoms lose electrons (oxidation) while oxygen atoms gain electrons (reduction).
True or false the burning of wood is an example of an oxidation-reduction reaction?
True. The burning of wood involves the oxidation of wood (losing electrons) by oxygen in the air, resulting in the release of energy in the form of heat and light. This is a classic example of an oxidation-reduction (redox) reaction.
Which reaction are of oxidation reaction and are of exothermic nature?
These are not mutually exclusive. A reaction can be oxidation and exothermic. Oxidation reactions involve a change in oxidation state (charge) which is interpreted as a loss of electrons. Exothermic reactions release heat energy.
Combustion is an example of?
A chemical reaction specifically oxidation

What is an example of oxidation reduction reaction?
When tarnish forms on silver
Give an example of an oxidation reaction and tell which substance loses electrons?
An example of an oxidation reaction is the reaction between magnesium and oxygen to form magnesium oxide: 2Mg + O2 -> 2MgO. In this reaction, magnesium loses electrons to form magnesium ions, Mg²⁺, thereby undergoing oxidation.
Rusting of steel is?
A good example of an oxidation reaction. The rusting of steel is essentially just rusting (oxidation) of iron.
Is oxidation reaction a single replacement reaction?
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.

Hematite
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
