Answer 1

Balancing Chemical Equations:

1) FeS + HNO₃ → Fe(NO₃)₃ + H₂S - The balanced equation is: FeS + 6HNO₃ → Fe(NO₃)₃ + 3H₂S [[1]].

2) CuSO₄ + BaCl₂ → CuCl₂ + BaSO₄ - The balanced equation is: CuSO₄ + BaCl₂ → CuCl₂ + BaSO₄ [[2]].

3) Al + H₂SO₄ → Al₂(SO₄)₃ + H₂ - The balanced equation is: 2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂ [[3]].

4) 4Al + 3O₂ → 2Al₂O₃ - The balanced equation is: 4Al + 3O₂ → 2Al₂O₃ [[4]].

5) ZnO + H₃PO₄ → Zn₃(PO₄)₂ + H₂O - The balanced equation is: 3ZnO + 2H₃PO₄ → Zn₃(PO₄)₂ + 3H₂O [[5]].

6) C₂H₂ + 5O₂ → 2CO₂ + 2H₂O - The balanced equation is: 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O [[6]].

7) Ag₂SO₄ + BaCl₂ → 2AgCl + BaSO₄ - The balanced equation is: Ag₂SO₄ + 2BaCl₂ → 2AgCl + BaSO₄ [[7]].

8) 4Li₃P + 10O₂ → 6Li₄P₂O₇ - The balanced equation is: 4Li₃P + 10O₂ → 6Li₄P₂O₇ [[8]].

9) C + O₂ → CO₂ - The balanced equation is: C + O₂ → CO₂ [[9]].

10) 2HCl + H₂SO₄ → 2H₂O + SO₂ + Cl₂ - The balanced equation is: 2HCl + H₂SO₄ → 2H₂O + SO₂ + Cl₂ [[10]].

Note: The coefficients in the balanced equations represent the relative number of molecules or moles of each substance involved in the reaction.
