Chapter 7, Problem 21A

Interpretation Introduction

Interpretation:

The unbalanced chemical equation corresponding to the reaction between ferric oxide and carbon monoxide needs to be presented.

Concept Introduction:

• A chemical reaction is expressed as a chemical equation having reactants and products on left and right side of the reaction arrow respectively.

  $\text{Reactants }\to \text{ Products}$

• It also gives the physical state (solid (s), liquid (l), gas (g) and the amount of reactants and products involved in the reaction.

Answer to Problem 21A

  ${\text{Fe}}_{\text{2}}{\text{O}}_3\text{(s) + CO(g) }\to {\text{ Fe (s) + CO}}_2\text{(g)}$

Explanation of Solution

The given process involves the reaction between ferric oxide solid and carbon monoxide gas at high temperatures to produce elemental iron and carbon dioxide gas. The reactants and products are:

Reactants:

  $\begin{array}{l}{\text{Ferric oxide, solid - Fe}}_{\text{2}}{\text{O}}_{\text{3}}(\text{s})\\ \text{Carbon monoxide, gas - CO (g)}\end{array}$

Products:

  $\begin{array}{l}\text{Iron, solid - Fe(s)}\\ {\text{Carbon dioxide, gas - CO}}_{\text{2}}\text{ (g)}\end{array}$

Unbalanced equation:

  ${\text{Fe}}_{\text{2}}{\text{O}}_3\text{(s) + CO(g) }\to {\text{ Fe (s) + CO}}_2\text{(g)}$

Conclusion

Therefore the unbalanced reaction will have ferric oxide solid and carbon monoxide gas as reactants with elemental iron and carbon dioxide gas as products.
