Based on the reactivity series, decide whether the following reaction will occur. If you think there

will be no reaction, write down why you think this. If you think a reaction will happen, write down
why you think it will happen, and the word equation to go with it.
a) iron heated with copper(II) oxide
b) aluminium heated with iron oxide
c) copper heated with iron oxide
d) magnesium heated with zinc oxide
e) tin into magnesium sulphate solution
f) copper dipped into silver nitrate solution
g) zinc dipped into lead nitrate solution

To determine whether a reaction will occur, we can use the reactivity series. The reactivity series is a list of metals in order of their reactivity. Metals higher in the reactivity series can displace metals lower in the series from their compounds.

a) Iron heated with copper(II) oxide: A reaction will occur. Iron is higher in the reactivity series than copper, so iron will displace copper from copper(II) oxide. The word equation for this reaction is: Iron + Copper(II) oxide → Iron(II) oxide + Copper.

b) Aluminium heated with iron oxide: A reaction will occur. Aluminium is higher in the reactivity series than iron, so aluminium will displace iron from iron oxide. The word equation for this reaction is: Aluminium + Iron oxide → Aluminium oxide + Iron.

c) Copper heated with iron oxide: No reaction will occur. Copper is lower in the reactivity series than iron, so it cannot displace iron from iron oxide.

d) Magnesium heated with zinc oxide: A reaction will occur. Magnesium is higher in the reactivity series than zinc, so magnesium will displace zinc from zinc oxide. The word equation for this reaction is: Magnesium + Zinc oxide → Magnesium oxide + Zinc.

e) Tin into magnesium sulphate solution: No reaction will occur. Tin is lower in the reactivity series than magnesium, so it cannot displace magnesium from magnesium sulphate.

f) Copper dipped into silver nitrate solution: A reaction will occur. Copper is higher in the reactivity series than silver, so copper will displace silver from silver nitrate. The word equation for this reaction is: Copper + Silver nitrate → Copper nitrate + Silver.

g) Zinc dipped into lead nitrate solution: A reaction will occur. Zinc is higher in the reactivity series than lead, so zinc will displace lead from lead nitrate. The word equation for this reaction is: Zinc + Lead nitrate → Zinc nitrate + Lead.

Remember, the reactivity series helps predict whether a reaction will occur based on the relative positions of elements in the series.

And where are YOUR answers? We HELP here but do not DO the work for you. If you ask questions about understanding something, that we can answer.

No effort on y our part means none on ours.
