Answer: The correct answer is Option B.
Explanation:
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
[tex]AB+CD\rightarrow CB+AD[/tex]
For the given options:
- Option A:
The chemical equation follows:
[tex]C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O[/tex]
This is a type of combustion reaction because an organic compound reacts with oxygen gas to produce carbon dioxide gas and water molecule
- Option B:
The chemical equation follows:
[tex]Rb_2O+Cu(C_2H_3O_2)_2\rightarrow 2RbC_2H_3O_2+CuO[/tex]
This is a type of double displacement reaction.
- Option C:
The chemical equation follows:
[tex]2Al+3H_2SO_4\rightarrow 3H_2+Al_2(SO_4)_3[/tex]
This is a type of single displacement reaction because a more reactive metal (aluminium) is replacing a less reactive metal (hydrogen).
- Option D:
The chemical equation follows:
[tex]2H_2O\rightarrow 2H_2+O_2[/tex]
This is a type of decomposition reaction because a single large compound is getting broken down to smaller substances.
Hence, the correct answer is Option B.
