In two or more complete sentences explain how to balance the chemical equation and classify its reaction type __AL(s) ± CuSO4(aq)

Balanced equation

2 Al(s) + 3 CuSo4(aq) = 3 Cu(s) + Al2(SO4)3(aq)

Reaction type : single replacement

Given

Al(s) ± CuSO4(aq)

Required

Balanced equation

Reaction type

Solution

Reaction

Al(s) + CuSo4(aq) = Cu(s) + Al2(SO4)3(aq)

aAl(s) + bCuSO4(aq) = cCu(s) + Al2(SO4)3(aq)

Al, left = a, right = 2⇒a=2

S, left = b, right = 3⇒b=3

Cu, left = b, right = c⇒c=b=3

The equation becomes :

2 Al(s) + 3 CuSo4(aq) = 3 Cu(s) + Al2(SO4)3(aq)

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds  

Not all of these reactions can occur. We can use the activity series(voltaic series). In this reaction, Al more reactive than Cu, so the reaction can occur.
