Final Answer:
1. N₂ + 3H₂ → 2NH₃
2. S₈ + 12O₂ → 8SO₃
3. 2HgO → 2Hg + O₂
4. Zn + 2HCl → ZnCl₂ + H₂
5. SiCl₄ + 4H₂O → H₄SiO₄ + 4HCl
6. 2Na + 2H₂O → 2NaOH + H₂
7. 4H₃PO₄ → 2H₄P₂O₇ + 2H₂O
8. Si₂H₆ + 7O₂ → 2SiO₂ + 6H₂O *(Note: Si₂H₃ is likely a typo; correct reactant is disilane, Si₂H₆)*
9. 2Al(OH)₃ + 3H₂SO₄ → Al₂(SO₄)₃ + 6H₂O
10. 4Fe + 3O₂ → 2Fe₂O₃
11. Fe₂(SO₄)₃ + 6KOH → 3K₂SO₄ + 2Fe(OH)₃
12. 4FeS₂ + 11O₂ → 2Fe₂O₃ + 8SO₂
13. 2Al + 3FeO → Al₂O₃ + 3Fe
14. Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂
15. 2K + Br₂ → 2KBr
16. P₄ + 5O₂ → P₄O₁₀ *(or 2P₂O₅ — but standard is P₄O₁₀)*
17. 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
