What are the coefficients that belong in the blanks to balance the following chemical equation?

__ iron (ii) sulfide + __ oxygen gas --> __ iron (iii) oxide + __ sulfur dioxide

4FeS + 5O₂ ⟶ 2Fe₂O₃ + 4SO₂

Explanation:

iron(II) sulfide + oxygen ⟶ iron(III) oxide + sulfur dioxide

1. Convert the word equation to a chemical equation:

FeS + O₂ ⟶ Fe₂O₃ + SO₂

2. Put a 1 in front of the most complicated-looking formula (Fe₂O₃):

FeS + O₂ ⟶ 1Fe₂O₃ + SO₂

3. Balance Fe:

We have fixed 2 Fe on the right. We need 2 Fe on the left. Put a 2 in front of FeS.

2FeS + O₂ ⟶ 1Fe₂O₃ + SO₂

4. Balance S:

We have fixed 2 S on the left. We need 2 S on the right. Put a 2 in front of SO₂.

2FeS + O₂ ⟶ 1Fe₂O₃ + 2SO₂

5. Balance O:

We have fixed 5 O on the right. We need 5 O on the left. Oops. We need a fraction to balance O.

6. Multiply all the coefficients by 2:

4FeS + O₂ ⟶ 2Fe₂O₃ + 4SO₂

7. Balance O:

4FeS + O₂ ⟶ 2Fe₂O₃ + 4SO₂

We have fixed 10 O on the right. e need 10 O on the left. Put a 5 in front of O₂.

4FeS + 5O₂ ⟶ 2Fe₂O₃ + 4SO₂

Every formula now has a coefficient. The equation should be balanced.

8. Check that atoms balance:

Atom  On the left  On the right

 Fe              4                   4

 S                4                   4

 O              10                 10

The balanced equation is

4FeS + 5O₂ ⟶ 2Fe₂O₃ + 4SO₂

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
