Question

Balance the equ. representing the reaction between iron

(III)oxide, Fe2O3 and carbon monoxide (CO) to yeild iron (Fe) and
carbondioxide (CO2).

Answer 1

The balanced chemical equation for the reaction between iron (III) oxide (Fe₂O₃) and carbon monoxide (CO) to yield iron (Fe) and carbon dioxide (CO₂) is: Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g).

Step-by-step explanation:

To balance the equation representing the reaction between iron (III) oxide (Fe₂O₃) and carbon monoxide (CO) to yield iron (Fe) and carbon dioxide (CO₂), we follow the basic principle of conservation of mass, which states that atoms must be conserved in a chemical reaction. The balanced chemical equation for this reaction is:

Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)

This equation indicates that one mole of iron (III) oxide reacts with three moles of carbon monoxide to produce two moles of iron and three moles of carbon dioxide. Note that this reaction is a combination of reduction of iron oxide and oxidation of carbon monoxide. Such reactions where both oxidation and reduction occur are known as redox reactions.

Answer 2

Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

Step-by-step explanation:

There are many ways to balance a chemical equation. In this case, I will show you the algebraic method:

The first step is assign a letter to each compound:

a Fe₂O₃ + b CO → c Fe + d CO₂

Then, you must write the balance equations for each atom, thus:

Fe: 2a = c

C: b = d

O: 3a + b = 2d

The last step is assign a value to a letter. I, for example, will say that a is 1, and then find the values for the others letters, thus:

Fe: 2a = c if a=1; c=2

O: 3a + b = 2d if a=1 → 3+b = 2d

As b = d → 3+d = 2d; 3 = 2d - d; 3=d and 3=b

Thus, the balanced equation is:

Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

I hope it helps!
