Can you help me solve this problem

**Iron Reacting with Oxygen to Form Iron(III) Oxide**

When iron reacts with oxygen at high temperatures, it forms iron(III) oxide according to the following chemical equation:

\[ 4 \text{Fe(s)} + 3 \text{O}_2\text{(g)} \rightarrow 2 \text{Fe}_2\text{O}_3\text{(s)} \]

Suppose 10.4 grams of iron (Fe) is reacted with 19.0 grams of oxygen (\(\text{O}_2\)).

**Select the Limiting Reagent:**

- \(\text{Fe}_2\text{O}_3\)
- \(\text{O}_2\)
- \(\text{Fe}\) (selected)

**Calculate the Theoretical Yield of Iron(III) Oxide (\(\text{Fe}_2\text{O}_3\)):**

- **Theoretical yield =** [Input Box for grams]

(Output indicates "Incorrect.")

**The Reaction Produces 5.79 g of \(\text{Fe}_2\text{O}_3\). What is the Percent Yield of the Reaction?**

- **Percent yield =** [Input Box for percent]

The image contains two input boxes, one for the theoretical yield in grams and another for the percent yield. It also identifies iron (\(\text{Fe}\)) as the limiting reagent.
