Which two reactions are opposites? synthesis and decomposition single-displacement and double-displacement

synthesis and decomposition

Explanation: Synthesis is a chemical reaction in which two or more than two reactants react together to form a single substance.

Decomposition is a chemical reaction in which a single reactant decomposes to give two or more than two products.

Single displacement reaction is the one which a more reactive element displaces a less reactive element from a solution.

Double displacement reaction is the one which exchange of ions take place.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
