1. Combustion of a substance is a/an a: reduction reactionsb: oxidation reactionc: displacement reactiond: decomposition reaction​

Answer» CORRECT option isA1All COMBUSTION reactions are OXIDATION-reduction reactions.For example, the combustion of oxygen is given by the following reaction:C+O 2 →CO 2 The oxidation number of elemental C and oxygen are 0 each.The oxidation number of C in CO 2 is +4 and the oxidation number of O in CO 2 is -2.Thus, C is oxidized and O is reduced.Hence, the combustion reaction is oxidation-reduction reaction.
