A synthesis reaction is when two or more chemical species combine to form a more complex product. The reactants maybe elements or compounds. The product is always a compound. An example of a Synthesis Reaction is 2 H2(g) + O2(g) → 2 H2O(g).
A decomposition reaction is a type of chemical reaction where one reactant yields two or more products. In a decomposition reaction, a compound is broken into smaller chemical species. An example of a Decomposition Reaction is 2 H2O → 2 H2 + O2.
Single Displacement Reaction
Double Displacement Reaction
A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions. An example of a Double Displacement Reaction is AB + CD → AD + CB.
