Reduction involves the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion. In the case of Cu2+ + 2 e− → Cu, Cu is reduced because its oxidation state decreases from +2 to 0.

A single reaction where oxidation and reduction take place is called?
a redox reaction
What type of reaction occurs when iron mixes with oxygen?
it forms iron oxide, and it can/should form rust
Are electrons lost when a chemical reaction is a reduction?
Reduction Is Gain of electrons

How do you figure out if a reaction is an oxidation or reduction reaction?
OIL RIG Oxidation is Loss Reduction is Gain... That's all I know =)
Single reaction where oxidation and reduction take?
half reaction
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
What is taking away the oxygen called?
This is a reduction reaction.
What type of reaction changes bauxite to aluminum metal?
A reduction reaction
What is the most completely describes a redox reaction?

What is the term for a reaction in which a substances gains electrons?
When a substance gains an electron or electrons, this is known as "reduction". For every reduction reaction, there is also an oxidation reaction. So, whatever substance "gave" the electrons, underwent oxidation.
Is oxidation-reduction the reaction that burning wood in a fireplace generate heat and light in the form of flames?
Burning wood in air/oxygen is a combustion reaction, a type of oxidation-reduction reaction.
What is chemical reaction with hydrogen called?
reduction
