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

Explanation:

Step1: Analyze each reaction

• For \(Ag + CuSO_4\to\): Silver (\(Ag\)) is less reactive than copper (\(Cu\)) (from the activity series \(Cu>Ag\)). So, this reaction will not occur.
• For \(Cu + Fe(NO_3)_2\to\): Copper (\(Cu\)) is less reactive than iron (\(Fe\)) (from the activity series \(Fe > Cu\)). So, this reaction will not occur.
• For \(Li+Zn(ClO_3)_2\to\): Lithium (\(Li\)) is more reactive than zinc (\(Zn\)) (from the activity series \(Li>Zn\)). So, this reaction will occur.
• For \(Pb + SnSO_4\to\): Lead (\(Pb\)) is less reactive than tin (\(Sn\)) (from the activity series \(Sn > Pb\)). So, this reaction will not occur.

Answer:

\(Li + Zn(ClO_3)_2\to\)
