Use the equation to answer the question.

CH4 + 2O2 → CO2 + 2H2O

If you change the 2 in front of 2O2
to a 3, what will be the change in the results on the right side of the equation?

If the 2 in front of 2O2 is changed to a 3, the change in the results on the right side of the equation will be that there will be an additional molecule of CO2 and two additional molecules of H2O.
