Chemical reactions are reactions in which elements or/and compounds combine chemically to form new substances.
There are different types of chemical reactions, they include
1. Combinations reactions
2. Decomposition reactions
3. Displacement reaction
4. Double decomposition reaction
5. Thermal Dissociation reaction
6. Catalytic reaction
1. Combination reaction: This is a type of reaction where two elements combine to form one single product.
C(s) + O2(g) CO2
2). Decomposition reactions:- In this type of reaction a single reactant split (decomposition) to give two or more products.
CaCO3(s) CaO(s)+ CO2(g)
When heat is applied to the reaction it is know as thermal decomposition.
3) Displacement reaction: this type of reaction occurs when one element or radical replaces another element or radical in a compound
