Rust:
2Fe + O2 --> 2FeO
Respiration:
C6H12O6 + 6O2 --> 6CO2 + 6H2O
There are chemical handbooks and journals filled with examples of oxidation reduction reactions.
Oxidation takes place at the anode in an electrochemical cell.
Oxygen can take part in a variety of reactions, such as combustion (burning), oxidation reactions, and reactions in biological processes like respiration. It is a highly reactive element that readily participates in chemical reactions.
The simple answer is not always. The stoicheometry deals with oxidation numbers only in redox reactions. The ratio of the change in oxidation numbers is straightly its stoicheometry.
Chemical reactions in the body take place in water.
Chemical reactions in the body take place in water.
There are a total of eight reactions that take place during the Krebs cycle. These reactions involve the oxidation of acetyl-CoA to produce carbon dioxide, ATP, and reducing equivalents. The cycle occurs in the mitochondrial matrix and is a key step in cellular respiration.
The most thermonuclear reactions on the sun, take place in the core.
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
By oxidation of organic substrates
In an electrochemical cell, oxidation occurs at the anode, where electrons are lost as a result of a redox reaction. The anode is where oxidation half-reactions take place, generating electrons that flow through the external circuit to the cathode. Reduction, on the other hand, occurs at the cathode, where electrons are gained during the redox reaction. This flow of electrons from anode to cathode is what generates an electric current in the cell.
Most of the body's chemical reactions take place within cells, specifically within organelles such as the mitochondria, where cellular respiration occurs, and the cytoplasm, where various metabolic processes take place. Enzymes play a crucial role in catalyzing these chemical reactions and maintaining the body's overall homeostasis.
