The correct response would be:

There are more carbons and oxygens on the left side than the right side.

Let's analyze the equation:

On the left side (reactants):

  • 1 carbon (from CH4)
  • 4 hydrogens (from CH4)
  • 4 oxygens (from 2 O2)

On the right side (products):

  • 1 carbon (from CO2)
  • 2 hydrogens (from H2O)
  • 3 oxygens (1 from CO2 and 2 from H2O)

This shows that the left side has more overall oxygen atoms compared to the right side, and the hydrogen is also unmatched. Additionally, the carbons are balanced. Therefore, the statement about more carbons and oxygens on the left side is accurate.
