<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

AB+CD\rightarrow CB+AD

For the given options:

  • <u>Option A:</u>

The chemical equation follows:

C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O

This is a type of combustion reaction because an organic compound reacts with oxygen gas to produce carbon dioxide gas and water molecule

  • <u>Option B:</u>

The chemical equation follows:

Rb_2O+Cu(C_2H_3O_2)_2\rightarrow 2RbC_2H_3O_2+CuO

This is a type of double displacement reaction.

  • <u>Option C:</u>

The chemical equation follows:

2Al+3H_2SO_4\rightarrow 3H_2+Al_2(SO_4)_3

This is a type of single displacement reaction because a more reactive metal (aluminium) is replacing a less reactive metal (hydrogen).

  • <u>Option D:</u>

The chemical equation follows:

2H_2O\rightarrow 2H_2+O_2

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.

How are sound waves and EM waves alike? How are they different?
Hatshy [7]
Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.
