Question

what is the balanced chemical reaction occurring when copper reacts with iron(ii) nitrate?
partial activity series
k ca mg al zn fe ni pb h cu ag
f₂ cl₂ br₂ i₂
no reaction occurs.
cu + fe(no₃)₂ → cu(no₃)₂ + fe
cu + 2feno₃ → cu(no₃)₂ + 2fe
cu + fe²⁺ → cu²⁺ + fe

Explanation:

To determine if a reaction occurs between copper (Cu) and iron(II) nitrate ($\ce{Fe(NO3)2}$), we use the activity series. In the activity series, a metal can displace another metal from its compound only if it is more reactive (higher in the series) than the other metal. Here, Fe is higher in the activity series than Cu, meaning Cu is less reactive than Fe. A less reactive metal cannot displace a more reactive metal from its compound. So, no reaction occurs between Cu and $\ce{Fe(NO3)2}$.

Answer:

No reaction occurs.
