THE FIVE REACTIONS OF CHEMISTRY

HAR HAR HAR.

There are five different reaction types. They are:

1. Synthesis: Two elements combining into a compound.



2. Decomposition: A compound that reacts to break down into its basic elements.



3. Single Replacement: A compound and a pure element in the reactant side will switch atoms, in the pattern metal/H with metal/H or halogens with halogens. AB + X -> AX + B



4. Double Replacement: Two or more compounds in the reactant side swap ions, sometimes a precipitate is formed. AB + XY -> AY + XB



5. Combustion: A reaction where hydrogen, oxygen, and carbon are always part of the reactants and carbon dioxide, water, and heat are the products. The reaction is also an exothermic reaction.
