2)2Fe(OH)3=Fe2O3+3H2O
3)2FePO4=Fe2O3+P2O5

Answer 2

To balance the chemical equations you provided, we'll start with each equation and adjust the coefficients in front of each compound until the number of atoms on both sides of the equation is balanced.

1. Fe₂S₃ + O₂ → Fe₂O₃ + SO₂

To balance the equation, we can start by balancing the iron (Fe) atoms:

Fe₂S₃ + O₂ → 2Fe₂O₃ + SO₂

Next, we balance the sulfur (S) atoms:

Fe₂S₃ + O₂ → 2Fe₂O₃ + 3SO₂

Finally, we balance the oxygen (O) atoms:

4Fe₂S₃ + 9O₂ → 8Fe₂O₃ + 6SO₂

Therefore, the balanced equation is: 4Fe₂S₃ + 9O₂ → 8Fe₂O₃ + 6SO₂.

2. Fe(OH)₃ → Fe₂O₃ + H₂O

This equation already has equal numbers of iron (Fe) atoms on both sides. To balance the oxygen (O) atoms, we add a coefficient of 3 in front of H₂O:

Fe(OH)₃ → Fe₂O₃ + 3H₂O

Now, the oxygen atoms are balanced. The equation is already balanced for hydrogen (H) atoms.

Therefore, the balanced equation is: Fe(OH)₃ → Fe₂O₃ + 3H₂O.

3. FePO₄ → Fe₂O₃ + P₂O₅

This equation has equal numbers of iron (Fe) atoms on both sides. To balance the phosphorus (P) atoms, we need a coefficient of 2 in front of P₂O₅:

FePO₄ → Fe₂O₃ + 2P₂O₅

Now, the phosphorus atoms are balanced. The equation is already balanced for oxygen (O) atoms.

Therefore, the balanced equation is: FePO₄ → Fe₂O₃ + 2P₂O₅.
