Answer 2

It looks like you've provided a list of chemical reactions and equations. Let's go through each one:

1. Fe + Cl2 → FeCl3 (Balanced equation: 2 Fe + 3 Cl2 → 2 FeCl3) Iron reacts with chlorine to form iron(III) chloride.

2. 4 Na + O2 → 2 Na2O Sodium reacts with oxygen to form sodium oxide.

3. 4 P + 5 O2 → 2 P2O5 Phosphorus reacts with oxygen to form diphosphorus pentoxide.

4. CuSO4 + Fe → FeSO4 + Cu Copper(II) sulfate reacts with iron to form iron(II) sulfate and copper.

5. 2 Fe(OH)3 + 6 HCl → 2 FeCl3 + 6 H2O Iron(III) hydroxide reacts with hydrochloric acid to form iron(III) chloride and water.

6. CaO + H2O → Ca(OH)2 Calcium oxide (quicklime) reacts with water to form calcium hydroxide (slaked lime).

7. Na2SO4 + BaCl2 → 2 NaCl + BaSO4 Sodium sulfate reacts with barium chloride to form sodium chloride and barium sulfate.

8. 2 H2O + 2 Na → 2 NaOH + H2 Water reacts with sodium to form sodium hydroxide and hydrogen gas.

9. FeCl2 + 2 NaOH → Fe(OH)2 + 2 NaCl Iron(II) chloride reacts with sodium hydroxide to form iron(II) hydroxide and sodium chloride.

10. Zn + 2 HCl → ZnCl2 + H2 Zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas.

11. Hg + S → HgS Mercury reacts with sulfur to form mercury(II) sulfide.

12. Al2O3 + 3 H2SO4 → Al2(SO4)3 + 3 H2O Aluminum oxide reacts with sulfuric acid to form aluminum sulfate and water.

13. Br2 → 2 HBr → 2 NaBr → NaNO3 Bromine undergoes several reactions to ultimately form sodium nitrate.

Please note that the reactions are written in a partially balanced form, and some of them might need further balancing depending on the specific context of the reaction conditions. If you have any further questions or need assistance with balancing these equations, feel free to ask!
