Answer 2

The balanced chemical equation for the given reactions is as follows:

1) Fe + H₂SO₄ → FeSO₄ + H₂↑ 2) FeSO₄ + KOH → Fe(OH)₂ + K₂SO₄ 3) Fe(OH)₂ → FeO + H₂O 4) FeO + HCl → FeCl₂ + H₂O

To balance these equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

1) Fe + H₂SO₄ → FeSO₄ + H₂↑ To balance this equation, we need to place a coefficient of 1 in front of Fe, 1 in front of H₂SO₄, 1 in front of FeSO₄, and 1 in front of H₂. The balanced equation is: Fe + H₂SO₄ → FeSO₄ + H₂↑

2) FeSO₄ + KOH → Fe(OH)₂ + K₂SO₄ To balance this equation, we need to place a coefficient of 1 in front of FeSO₄, 2 in front of KOH, 1 in front of Fe(OH)₂, and 1 in front of K₂SO₄. The balanced equation is: FeSO₄ + 2KOH → Fe(OH)₂ + K₂SO₄

3) Fe(OH)₂ → FeO + H₂O To balance this equation, we need to place a coefficient of 1 in front of Fe(OH)₂, 1 in front of FeO, and 1 in front of H₂O. The balanced equation is: Fe(OH)₂ → FeO + H₂O

4) FeO + HCl → FeCl₂ + H₂O To balance this equation, we need to place a coefficient of 1 in front of FeO, 2 in front of HCl, 1 in front of FeCl₂, and 1 in front of H₂O. The balanced equation is: FeO + 2HCl → FeCl₂ + H₂O

Please note that these balanced equations are based on the information provided. If there are any additional conditions or information, the equations may need to be adjusted accordingly.
