The NaCl was broken down into the constituents Na+ and Cl

−

2

--(side note: the Cl is diatomic that explains the 2)

There are two types of replacement reactions, observe the differences:

Single Replacement: AB+C→AC+B

double replacement reaction from chemistrycom

double replacement reaction from chemistrycom

Double Replacement: AB+CD→AD+CB
