Linking monomers using new bonds to form a long chain is an example of a/an reaction. a. addition b. subtraction c. substitution d. decomposition

Answer is: addition.

This is example of polymerization (addition of monomers to form polymer).

For example, plastic is organic polymers of high molecular mass derived from petrochemicals.

Another example, starch (carbohydrate) is a polymeric carbohydrate consisting of a large number of glucose units (monomers) bonded by glycosidic bond.

Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
