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?
pb + snso₄ →
ag + cuso₄ →
cu + fe(no₃)₂ →
li + zn(clo₃)₂ →

Explanation:

Step1: Analyze \(Pb + SnSO_4\)

Check reactivity. \(Sn\) is more reactive than \(Pb\) (from activity series \(Sn > Pb\)). So reaction won't occur.

Step2: Analyze \(Ag + CuSO_4\)

Check reactivity. \(Cu\) is more reactive than \(Ag\) (from activity series \(Cu>Ag\)). So reaction won't occur.

Step3: Analyze \(Cu + Fe(NO_3)_2\)

Check reactivity. \(Fe\) is more reactive than \(Cu\) (from activity series \(Fe > Cu\)). So reaction won't occur.

Step4: Analyze \(Li + Zn(ClO_3)_2\)

Check reactivity. \(Li\) is more reactive than \(Zn\) (from activity series \(Li>Zn\)). So reaction will occur.

Answer:

Only \(Li + Zn(ClO_3)_2\) reaction will occur.
