WebThe 5 primary types of chemical reactions are: Combination reaction Decomposition reaction Displacement reaction Double Displacement reaction Precipitation Reaction 1. Combination Reaction A reaction in which two or more reactants combine to form a single product is known as a combination reaction. It takes the form of X + Y → XY WebPart 4: A chemical reaction is a rearrangement of atoms. In the fourth and final part of Dalton's atomic theory, he suggested that chemical reactions don't destroy or create atoms. They merely rearranged the atoms. Using our salt example again, when sodium combines with chlorine to make salt, both the sodium and chlorine atoms still exist.
