Question

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type.

Answer 1

Answer: The given chemical reaction is a single displacement reaction.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive metal displaces the less reactive metal from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

$A+BC\rightarrow AC+B$

Metal A is more reactive than Metal B.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

For the given chemical reaction:

$2Al(s)+3CuSO_4(aq.)\rightarrow Al_2(SO_4)_3(aq.)+3Cu(s)$

By Stoichiometry of the reaction:

2 moles of aluminium metal reacts with aqueous solution of copper sulfate to produce 1 mole of aqueous solution of aluminium sulfate and 3 moles of copper metal.

Hence, the given chemical reaction is a single displacement reaction.
