Question

Pb+H2SO4(разб) --->Al+Hg(NO3)2 --->Zn+MgCl --->Fe+ZnCl --->

Answer 1

O2 + H2SO4(разб.) + Pb = PbSO4↓ + H2O2

Al + 3HgNO3 = Al(NO3)3 + 3Hg

Zn + MgCl = ZnCl + Mg

Fe + ZnCl = FeCl2 + Zn

Answer 2

Balanced Chemical Equations:

The given chemical reactions can be represented by the following balanced chemical equations:

1. Pb + H2SO4 (dilute) → PbSO4 + H2O - Lead (Pb) reacts with dilute sulfuric acid (H2SO4) to form lead sulfate (PbSO4) and water (H2O).

2. Al + Hg(NO3)2 → Al(NO3)3 + Hg - Aluminum (Al) reacts with mercury(II) nitrate (Hg(NO3)2) to form aluminum nitrate (Al(NO3)3) and mercury (Hg).

3. Zn + MgCl2 → ZnCl2 + Mg - Zinc (Zn) reacts with magnesium chloride (MgCl2) to form zinc chloride (ZnCl2) and magnesium (Mg).

4. Fe + ZnCl2 → FeCl2 + Zn - Iron (Fe) reacts with zinc chloride (ZnCl2) to form iron(II) chloride (FeCl2) and zinc (Zn).

Please note that the given reactions are balanced chemical equations, representing the stoichiometry of the reactants and products involved in the reactions.
