  • A synthesis reaction occurs when two or more reactants combine to form a single product. ... An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl). This reaction is represented by the chemical equation: 2Na + Cl2 → 2NaCl.
  • A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

When a strip of zinc metal is placed in iron sulphate solution,then a displacement reaction take place to form zinc sulphate solution and iron metal. Zinc metal displaces iron metal from iron sulphate solution. This displacement reaction takes place because zinc is more reactive than iron.

A double-replacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products. An example is. CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)
