The chemical reaction na+ + cl- nacl is best described as a(n)
decomposition reaction
exchange reaction
reversible reaction
synthesis reaction

The correct answer is:

synthesis reaction

Explanation:

A combination reaction or direct incorporation reaction is a type of chemical reaction in which two or more simple materials combine to form a more intricate product. The reactants may be elements or compounds. The product is always an aggregate.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

you need to have a picture of the atom that way we can answer it
