Answer:
formation of CU from copper and oxygen denote -:
(a) reduction (b) oxidation
(c) redox reaction✔ (d) none of these
Answer:
The formation of CUo from copper and oxygen denotes a redox reaction or combination reaction that occurred.
Explanation:
As per the given statement, there are two situations,
Firstly, The formation of copper oxide (CuO) from copper and oxygen would be an example of an oxidation reaction.
An oxidation reaction is a chemical reaction where a substance (the oxidizing agent) gains oxygen atoms and loses electrons. In this case, the copper is oxidized as it gains oxygen atoms from the oxygen molecule to form copper oxide (CuO).
On the other hand, a reduction reaction is a chemical reaction where a substance (the reducing agent) loses oxygen atoms and gains electrons. A redox reaction (reduction-oxidation reaction) is a type of chemical reaction that involves both oxidation and reduction reactions, and the transfer of electrons from one substance to another.
In this case, only an oxidation reaction has taken place, so the answer would be (b) oxidation.
But since, the timings and states aren't mentioned, so
The formation of CUo from copper and oxygen denotes a redox reaction or combination reaction that occurred. In a redox reaction reduction of one substance and oxidation of other substances takes place simultaneously.
A redox reaction can be defined as a chemical reaction in which electrons are transferred between two reactants participating in it. This transfer of electrons can be identified by observing the changes in the oxidation states of the reacting species.
