Question

Use the activity series to predict if there will be a reaction in the following cases. If a reaction does not occur write “no reaction”, but if a reaction occurs, write a balanced equation.
Fe + Pb(NO3)2 → Pb + Fe(NO3)2

Cu + Al2(SO4)3

Answer 1

Explanation:

in the first case the reaction takes place because iron is more reactive than lead.

balanced equation-

Fe + Pb(NO3)2 → Pb + Fe(NO3)2

in the second case the reaction will not take place because copper is less reactive than alluminium.

Answer 2

Answer:

Fe + Pb(NO3)2 → Pb + Fe(NO3)2.

Cu + Al2(SO4)3 → No Reaction Occurs

Explanation:

Fe is more reactive than so it can displace lead. So the reaction occurs and it is a balanced chemical equation.

Copper can't displace Aluminium as it is less reactive than Aluminium. So no reaction occurs.
