Prepare a detailed report on Types of Chemical reactions (20 each)
Answers
Different types of chemical reaction are:
(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. CaCO3ΔCaO+CO2
(c) Displacement reaction: The reaction in which more reactive metal displaces the less reactive metal is called displacement reaction.
e.g. Fe+CuSO4→FeSO4+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. Na2SO4(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.
The reaction in which hydrogen is added/ oxygen in removed is called reduction reaction.

Answer:
Different types of chemical reaction are:
(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. CaCO3 ---- CaO+CO2
(c) Displacement reaction: The reaction in which more reactive metal displaces the less reactive metal is called displacement reaction.
e.g. Fe+CuSO4 →FeSO4 +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. Na2SO4(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.
