Question

Oxidation reaction and Reduction reaction​

Answer 1

oxidation reactions are those when a substrate is oxidized by an oxidant so that atoms of the substrate increase their oxidation numbers while atoms of the oxidant are reduced.

Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.

A reduction reaction is one in which a reactant in a chemical reaction gains one or more electrons. Reduction reactions always occur in conjunction with oxidation reactions, in which a reactant loses one or more electrons.

example CuO+H2heat Cu+H2O.

Answer 2

Answer:

Oxidation is the gain of oxygen. Reduction is the loss of oxygen. For example, in the extraction of iron from its ore
