The reaction of a metal with oxygen to form rust is called as redox reaction.
Explanation:
The process during which the surface of metal reacts with the oxygen ions present in air, it has tendency to get oxidized that is formation of an oxide layer on the surface of the metal. Generally, it occurs when metals like iron comes in contact with moisture or water. So the oxygen in moisture reacts with iron giving its electron and getting oxidized and reducing the surface of metal by forming metal oxide. So the complete process of formation of rust is termed as redox reaction. As here both oxidation and reduction is taking place.

Explanation:
1. Precision is how close experimental values are to one another or also defined as the reproducibility of a result i.e. the ability to reproduce a measurement.
2. Instrument precision, also called Injection precision, is the reproducibility of an instrument reading when the same amount of one sample of what is being measures is introduced repeatedly into an instrument.
3. Intra-assay precision is the reproducibility of measurements on the same material several times by one person on one day with the same equipment.
4. Intermediate precision is also called Ruggedness and it refers to the reproducibility of measurements by different people, on different days, on different pieces of equipment within the same laboratory.
5. Interlaboratory precision is the reproducibility of a measurement from the same sample by different people in different laboratories
