Answer:
(a) Combination reactions: The reaction in which two or more than two substance combine together to form a single compound.
e.g. 2Mg+O2 →2MgO
(b) Decomposition reaction: The reaction in which a compound decomposes to form two or more substance is called decomposition reaction.
e.g. CaCO 3 -> CaO+CO 2
(c) Displacement reaction: The reaction in which more reactive metal displaces the less reactive metal is called displacement reaction.
e.g. Fe+CuSO 4 → FeSO 4+Cu
(d) Double displacement reaction: The reaction in which two different atoms or groups of (substance) atoms exchange for each other is called double displacement reaction.
e.g. Na 2SO 4 (aq)+BaCl2 (aq) → BaSO4(s)+2NaCl(aq)
(e) Oxidation reduction reaction: The reaction in which oxygen is added/ hydrogen is removed is called oxidation reaction.
e.g.
The reaction in which hydrogen is added/ oxygen in removed is called reduction reaction.
