A chemical reaction is the change of a substance into a new one that has a different chemical identity.
I'll give you an example of formation of Aluminum Bromide:
When Al is placed on the surface of liquid Br2an exothermic reaction occurs. The Al is oxidized to Al3+ by the Br2, which is reduced to Br - ions. The ionic product, AlBr3, can be observed on the watch glass after the reaction.
Chemical reactions are of 4 types-synthesis, decomposition, single replacement and double replacement.
Hope this helps..!!
