Any reaction that doesn't have at least one atom that increases in oxidation number during the reaction and at least one atom that decreases in oxidation number during the reaction is not a redox reaction. The atom that decreases and the atom that increases can be atoms of the same element.
Examples:
2H2 + O2 --> 2H2O ( Atoms of elements have an oxidation number of 0, so that the hydrogen atoms change from 0 to +1, which is oxidation, while the oxygen atoms change from 0 to -2, which is reduction. So the reaction is a redox reaction.)
An example of a reaction in which atoms of the same element undergo both oxidation and reduction is:
2 MnO4- (aq) + 5 Mn (s) + 16 H+ (aq) -> 7 Mn+2 (aq) + 4 H2O (l).
(In this reaction, 2 manganese atoms change from +7 to +2, which is reduction, and 5 manganese atoms change from 0 to +2, which is oxidation. )
An example of a non-redox reaction is
Pb(NO3)2 (aq) + Na2SO4 (aq) ---> 2 NaNO3 (aq) + PbSO (s).
(No atom changes its oxidation state in this reaction.)

In a redox reaction, there is a change in the oxidation state of two or more reacting species whereas there is no change in oxidation sate of any species in a non-redox reaction.
Redox : H2 + F2 → 2 HF
Here H and F changes from zero O.S. to +1 and -1 respectively.
Non-redox: FeSO4 + CaS -> CaSO4 + FeS
Ex: CaO + CO2 --> CaCO3 This would not involve oxidation or reduction.
A reaction in which oxidation and reduction take place simultaneously is called a redox reaction.
So, a non-redox reaction would be a chemical reaction with only one process.
examples of basis and acids in our daily life
Burning wood is exothermic and photosynthesis is endothermic.
The reaction between hydrogen and oxygen to form water is represented by the following equation. 2 H2 + O2 2 H2O
Examples are: oxidation, hydrolysis, thermal decomposition, interactions between wastes.
You can find these online or in your textbook. They would be great to use in an experiment or a project.
paper burning.
Photosynthesis.
The photosynthesis is an endothermic reaction that takes place everyday.

Examples of a reaction paper during a field trip can be found at most local libraries. Examples can also be found in teaching periodicals.
Some examples of reaction engines in airplanes are turbofans and turbojets.
Anything burning, oxidising, exploding etc.
Nope - they're an example of a chemical reaction.
well the chemical reaction is cooking not physical
