1- Reaction of an acid with a base. 2-Displacement reactions of ionic compounds.
This type of reaction is called a 'reduction'. (The opposite to 'oxidation')
This reaction can be called "deoxidation" or "reduction".
corrosion (in iron this is called rusting)
Iron(II) indicates that the cation is Fe2+. The (II) indicates the oxidation number of iron in this case it has lost 2 electrons. ( OILRIG -oxidation is loss (of electrons), reduction is gain).
Fire(Burning) is a chemical change. Once you burn a log, you won't get the log back, that's how it's a chemical change. Also, Fire needs Oxygen (O2) to burn and stay alive but with too much Carbon Dioxide (CO2) it will die out.
another name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
This type of reaction is called a 'reduction'. (The opposite to 'oxidation')
The general term is "chemical reaction". There are sub-categories like "oxidation-reduction", "double (and single) replacement", and others.
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.
This reaction can be called "deoxidation" or "reduction".
The corrosion of metals involves a redox reaction. In an oxidation-reduction or redox reaction, metals lose electrons to oxygen to form a ionic compound from the metal ions and an ion of the oxide.
Aerobic
Oxidation
corrosion (in iron this is called rusting)
This substance is called an Oxidant or an Oxidising Agent .It oxidises the other substance and reduces itself .
oxidation.... I think
This is an oxidation reaction (burning of ethanol).
