Fill in the table to show the number of atoms in the reaction below.

a chemical reaction between methane and oxygen produces carbon dioxide and water. On the left of the arrow, a central black circle is connected to four white circles, representing methane. Two sets of two red circles connected to each other represent oxygen. On the right of the arrow, two red circles are connected to a central black circle, representing carbon dioxide. Two sets of two white circles connected to a central red circle represent water.

To fill in the table showing the number of atoms in the reaction between methane (CH₄) and oxygen (O₂) that produces carbon dioxide (CO₂) and water (H₂O), we first need to determine the number of each type of atom present in both the reactants and products:

  1. Reactants:

    • Methane (CH₄): 1 carbon (C) atom and 4 hydrogen (H) atoms.
    • Oxygen (O₂): 2 oxygen (O) atoms.

    Total for the reactants:

    • Carbon: 1 (from CH₄)
    • Oxygen: 2 (from O₂)
    • Hydrogen: 4 (from CH₄)

  2. Products:

    • Carbon Dioxide (CO₂): 1 carbon atom and 2 oxygen atoms.
    • Water (H₂O): 2 hydrogen atoms.

    Total for the products:

    • Carbon: 1 (from CO₂)
    • Oxygen: 2 (1 from CO₂ and 1 from H₂O, which totals to 2 for both)
    • Hydrogen: 2 (from H₂O)

Now let's fill out the table:

| Reactants | Products | |-------------|------------| | Carbon (black) | 1 | 1 | | Oxygen (red) | 4 | 2 | | Hydrogen (white) | 4 | 2 |

So, the completed table should have:

  • Reactants:

    • Carbon (black): 1
    • Oxygen (red): 4
    • Hydrogen (white): 4

  • Products:

    • Carbon (black): 1
    • Oxygen (red): 2
    • Hydrogen (white): 2

The final counts for reactants and products are consistent with the balanced equation for the combustion of methane.
