Oxygen (O)

Answer 1

To fill in the table based on the chemical equation \( 4Fe + 3O_2 \rightarrow 2Fe_2O_3 \) and the corresponding atom counts:

Reactants:

• Iron (Fe): 4 atoms
• Oxygen (O): 6 atoms (since \( 3O_2 \) indicates 3 molecules of O2, each containing 2 oxygen atoms)

Products:

• Iron (Fe): 4 atoms (since \( 2Fe_2O_3 \) indicates 2 molecules of Fe2O3, each containing 2 iron atoms)
• Oxygen (O): 6 atoms (since \( 2Fe_2O_3 \) indicates 2 molecules of Fe2O3, each containing 3 oxygen atoms)

Now, the table can be filled out as follows:

| | Reactants | Products | |-------------|-----------|----------| | Iron (Fe) | 4 | 4 | | Oxygen (O) | 6 | 6 |

Feel free to drag and drop the values into the table as needed!
