Types of Reactions and Examples of Inorganic compounds

There are about four types of chemical reactions in Inorganic chemistry namely combination, decomposition, single displacement and double displacement reactions.

1. Combination Reactions: As it is in the name ‘Combination’, here two or more substances combine to form a product which is called a Combination reaction. For example: Barium + F₂ → BaF₂
2. Decomposition Reaction: It is a type of reaction where a single element splits up or decomposes into two products. For example: FeS → Fe + S
3. Single Displacement Reactions: A reaction where a single atom of one element replaces another atom of one more element. For example: Zn (s) + CuSO₄ (aq) → Cu (s) + ZnSO₄ (aq)
4. Double Displacement Reactions: This type of reaction is also called ‘metathesis reactions’. Here two elements of two different compounds displace each other to form two new compounds. For example:CaCl₂ (aq) + 2AgNO₃ (aq) → Ca(NO₃)₂ (aq) + 2 AgCl (s)
