Carbon monoxide reacts with iron to form

Options

A. `Fe(CO)_(5)`
B. `FeCO_(3)`
C. `FeO+C`
D. `Fe_(2)O_(3)+C`

Explanation

To solve the question of what carbon monoxide reacts with iron to form, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are carbon monoxide (CO) and iron (Fe).

### Step 2: Determine the Possible Products
When carbon monoxide reacts with iron, it can potentially form iron oxides. The most common iron oxides are:
- FeO (Iron(II) oxide)
- Fe2O3 (Iron(III) oxide)

### Step 3: Write the Balanced Chemical Equation
To find out what products are formed, we need to balance the reaction. The balanced equation for the reaction of carbon monoxide with iron can be represented as follows:

\[ 3 \text{CO} + 2 \text{Fe} \rightarrow \text{Fe}_2\text{O}_3 + 3 \text{C} \]

### Step 4: Analyze the Products
From the balanced equation, we can see that when carbon monoxide reacts with iron, it produces iron(III) oxide (Fe2O3) and carbon (C).

### Step 5: Conclusion
Thus, the final answer to the question "Carbon monoxide reacts with iron to form" is:
\[ \text{Fe}_2\text{O}_3 + \text{C} \]
