It looks like you have a list of chemical reactions, but they need balancing. Here are the balanced equations for each reaction:

1. C + O₂ → CO

   • Balanced: C + O₂ → CO

2. Cu(OH)₂ → CuO + H₂O

   • Balanced: Cu(OH)₂ → CuO + H₂O (This is already balanced.)

3. KOH + H₃PO₄ → K₃PO₄ + H₂O

   • Balanced: 3 KOH + H₃PO₄ → K₃PO₄ + 3 H₂O

4. NaI + Cl₂ → NaCl + I₂

   • Balanced: 2 NaI + Cl₂ → 2 NaCl + I₂

5. NaNO₃ → NaNO₂ + O₂

   • Balanced: 2 NaNO₃ → 2 NaNO₂ + O₂ (This reaction is not typically represented with coefficients, but it may need two of each compound to balance properly.)

6. Al + Cl₂ → AlCl₃

   • Balanced: 2 Al + 3 Cl₂ → 2 AlCl₃

7. Fe + HCl → FeCl₂ + H₂

   • Balanced: Fe + 2 HCl → FeCl₂ + H₂

8. Ba(NO₃)₂ + H₂SO₄ → BaSO₄ + HNO₃

   • Balanced: Ba(NO₃)₂ + H₂SO₄ → BaSO₄ + 2 HNO₃

9. Li + O₂ → Li₂O

   • Balanced: 4 Li + O₂ → 2 Li₂O

10. CuO + HCl → CuCl₂ + H₂O

    • Balanced: CuO + 2 HCl → CuCl₂ + H₂O

Make sure to check each reaction, as some may require specific conditions to occur, and the products may vary depending on these conditions. If you need further explanation or assistance, feel free to ask!
