Answer 1

Explanation:

1. 2NaI + F₂ → 2NaF + I₂
2. 3Ca + N₂ → Ca₃N₂
3. Pb(ClO₂)₄ + 2ZnSO₄ → Pb(SO₄)₂ + 2Zn(ClO₂)₂
4. 2LiOH → Li₂O + H₂O
5. 4Cr + 3O₂ → 2Cr₂O₃
6. KClO₄ → KCl+ 2O₂
7. Ni(OH)₂ + H₂SO₄ → NiSO₄ + 2H₂O
8. 4Ga(CN)₃ + 3Sn(BrO₃)₄ → 3Sn(CN)₄ + 4Ga(BrO₃)₃
9. 3Ca(NO₃)₂ + 2Fe → 2Fe(NO₃)₃ + 3Ca
10. 2Al + 6HCl → 2AlCl₃ + 3H₂
11. Ba(C₂O₄) + 2KIO₃ → Ba(IO₃)₂ + K₂(C₂O₄)
12. 2Cs + Sr(CrO₄) → Cs₂(CrO₄) + Sr
