Question

based on the activity series, which of the reactions will occur?
most reactive
least reactive
li na k mg al zn fe ni sn pb h cu ag pt
f₂ cl₂ br₂ i₂
hint: is the free element more reactive than the one in the compound?
ag + niso₄ →
sn + fe(no₃)₂ →
pb + zn(no₃)₂ →
fe + snso₄ →

Explanation:

Step1: Analyze \(Ag + NiSO_4\)

Check reactivity of \(Ag\) and \(Ni\). From the series, \(Ag\) is less reactive than \(Ni\). So, \(Ag\) cannot displace \(Ni\) from \(NiSO_4\).

Step2: Analyze \(Sn + Fe(NO_3)_2\)

Check reactivity of \(Sn\) and \(Fe\). From the series, \(Sn\) is less reactive than \(Fe\). So, \(Sn\) cannot displace \(Fe\) from \(Fe(NO_3)_2\).

Step3: Analyze \(Pb + Zn(NO_3)_2\)

Check reactivity of \(Pb\) and \(Zn\). From the series, \(Pb\) is less reactive than \(Zn\). So, \(Pb\) cannot displace \(Zn\) from \(Zn(NO_3)_2\).

Step4: Analyze \(Fe + SnSO_4\)

Check reactivity of \(Fe\) and \(Sn\). From the series, \(Fe\) is more reactive than \(Sn\). So, \(Fe\) can displace \(Sn\) from \(SnSO_4\). The reaction \(Fe + SnSO_4=FeSO_4 + Sn\) will occur.

Answer:

\(Fe + SnSO_4\to\)
