✴TYPES OF CHEMICAL REACTIONS✴
----------------------------------------------------------------------------------------------------

✨Identify the type of Reaction given below :

1. COMBINATION REACTION : as Calcium Oxide ( CaO) combines with water (H2O) to form a single product Calcium Hydroxide Ca(OH)2.

2. DECOMPOSITION REACTION : As Calcium Carbonate ( CaCO3) splits or decomposes into Calcium Oxide and Carbon dioxide.

3. SINGLE DISPLACEMENT REACTION : As Zinc being more reactive than copper,displaces it from its aqueous solution.

4. DECOMPOSITION REACTION : As Ferrous sulphate decomposes into ferric oxide sulphur dioxide and Sulphur trioxide.

5. DOUBLE DISPLACEMENT REACTION : As an exchange of ions takes place between Barium chloride and Sodium sulphate . It leads to the formation of white insoluble precipitate of Barium chloride.
