Expert Solution

Step 1

Types of chemical reactions-

There are five types of chemical reactions-

1. Combination reaction-A new substance formation by combination (mixing) of two substances.

e.g. $2 N a + C l_{2} \to 2 N a C l$

2. Decomposition reaction-breaking of large molecule into small molecules or simpler substances.

$e . g . N a_{2} C O_{3} \to 2 N a O + C O_{2}$

3. Single displacement reaction-replacement of one element by similar element in an another molecule in a reaction.

$e . g . C u + Z n S O_{4} \to C u S O_{4} + Z n$

4. Double displacement reaction-in reaction positive and negative ions of two ionic compounds displaces each other to form new compounds.

$e . g . P b N O_{3} + K I \to P b I_{2} + K N O_{3}$

Precipitation reaction is a subtype of double displacement reaction in which combination of two aqueous ionic compounds to forms insoluble residue called as precipitation reaction.

5. Combustion reaction-the reaction in which substance reacts with oxygen gas or air called as combustion reaction.

$e . g . C + \frac{1}{2} O_{2} \to C O$
