Question

Fill in the coefficients that will balance the following reaction:

(Note: Use 1 as coefficient where appropriate.)
CH4 +
02 →
CO₂ +
H₂O

Answer 1

CH4 + 2O2 ⇒ CO2 + 2H2O

Step-by-step explanation:

Balancing Chemical Equations

CH4 + O2 ⇒ CO2 + H2O

First, balance the carbons:

CH4 + O2 ⇒ CO2 + H2O

Then, balance the hydrogens:

CH4 + O2 ⇒ CO2 + 2H2O

Finally, balance the oxygens:

CH4 + 2O2 ⇒ CO2 + 2H2O
