Question
Use the equation to answer the question.
CHA+ 202→CO2+2H20
If you change the 2 in front of 20½ to a 3, what will be the change in the results on the right side of the equation?
(1 point)
• Nothing changes in the equation
• There is an extra O2 molecule left over
3: There are now 3 H2O molecules
4: There are now 3 CO2 molecules

Answer: There is an extra O2 molecule left over.
Explanation: CH4 + 2O2 → CO2 + 2H2O needs 2 O2 per CH4. If you supply 3 O2, only 2 are consumed, so the products stay CO2 and 2 H2O and one O2 remains unreacted.
