Answer:
1 the loss of electrons by the compounds in the chemical reactions.2 on the left side(reactant) 3 it the the reactant that being"s oxidized 4 The compound which gains electron in the redox reaction.
Explanation:
In a redox reaction the compound the loses electrons is oxidized the phenomenon of electron loss is known as oxidation
Electron appear on the left side(reactant) of an oxidation half reaction
Oxidant is the reactant that"s being oxidized
oxidizing agent are the compounds which gains electron in the redox reaction.
