what is a chemical reaction ? explain the different types of chemical reaction and give example of each of the following.
Answers
Answer:
The transformation of chemical substance into a new chemical substance by making and breaking of bonds between different atoms is known as Chemical Reaction.
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.

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. CCaCO3 ----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+CCuSO →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. Na2 SO4 (aq)+BaCl 2 (aq)→BaSO 4 (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.
