Question

write about different types of chemical reactions?​

Answer 1

Answer:

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.

Explanation:

Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.

Answer 2

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+O

2

→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

Δ

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

2

SO

4

(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.

Example oxidation of copper shown in image

The reaction in which hydrogen is added/ oxygen in removed is called reduction reaction.
