1) 2 NaNO₃ + PbO → Pb(NO₃)₂ + Na₂O
2) 6 AgI + Fe₂(CO₃)₃ → 2 FeI₃ + 3 Ag₂CO₃
3) 2 C₃H₄O₂ + 7 O₂ → 6 CO₂ + 4 H₂O
4) 3 ZnSO₄ + Li₂CO₃ → ZnCO₃ + Li₂SO₄ (Note: This equation cannot be balanced as written because the products do not match the reactants stoichiometrically; likely a typo — if intended to be 3ZnSO₄ + 3Li₂CO₃ → 3ZnCO₃ + 3Li₂SO₄, then coefficients are all 3. But as written, it’s unbalanced and chemically incorrect.)
5) 2 V₂O₅ + 5 CaS → 5 CaO + V₂S₅
6) Mn(NO₂)₂ + BeCl₂ → Be(NO₂)₂ + MnCl₂
7) 3 AgBr + GaPO₄ → Ag₃PO₄ + GaBr₃
8) 3 H₂SO₄ + 2 B(OH)₃ → B₂(SO₄)₃ + 6 H₂O
9) S₈ + 8 O₂ → 8 SO₂
10) Fe + 2 AgNO₃ → Fe(NO₃)₂ + 2 Ag
