Question

define oxidation and reduction by activities​

Answer 1

Answer:

Reduction involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. ... Here, oxidation is the gain of oxygen, while reduction is the loss of oxygen. An old, less-common definition of oxidation and reduction examines the reaction in terms of protons or hydrogen.

Answer 2

Answer:

the answer is down

Explanation:

In an oxidation-reduction, or redox, reaction, one atom or compound will steal electrons from another atom or compound. A classic example of a redox reaction is rusting. When rusting happens, oxygen steals electrons from iron. Oxygen gets reduced while iron gets oxidized.
