What is true of a decomposition reaction? the reactants are usually a metal and a nonmetal. the reactants are generally two ionic compounds in an aqueous solution. the addition of energy in the form of heat or electricity is often required. water is usually one of the reactants.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
