Best Answer

They're both types of chemical reactions. In a decomposition reaction one compound is broken into two parts. Ex) HCl yields H + Cl

In a synthesis reaction the opposite happens. You begin with two elements or compounds and end with one product. Ex) K + I yields KI These are obviously simplified versions but they convey the point.
