rust or tarnish
Respiration.
This is an oxidation reaction.
The oxidation is called "combustion" (i.e. burning).
The reaction of oxygen with other elements is oxidation. An example is iron and oxygen reacting to form rust.
Redox reaction (reduction-oxidation).
Respiration.
The process in which metal rusts is called oxidation. This happens usually when water is present and the oxygen can bond with the metal releasing hydrogen into the air.
This is an oxidation reaction.
This is an oxidation reaction (combustion, burning).
Copper reacts with the oxygen in the air in a process called oxidation. This occurs in several steps as seen in Kuba Jasinski’s answer. The reactions occur as the copper atoms give up some electrons (oxidation) to the oxygens (reduction) to create ionic compounds. This is a classic example of what is called a redox (reduction-oxidation) reaction.

Redox reaction (reduction-oxidation).
This is a reaction of oxidation.
Rust just ignore the top word its wrong the answer is oxidation
Because combustion is a reaction with oxygen.
