Question

Balance the chemical equation : 
CH₄ + O₂ → CO₂ + H₂O

Florisalreadytaken · Answer

$ CH_4 + O_2 \ \rightarrow \ CO_2 + H_2O $ C = 1 C = 1 H = `4` H = `2` -- ill balance this first O = 2 O = 3

$ CH_4 + O_2 \ \rightarrow \ CO_2 + 2 H_2O $ now we have got: C = 1 C = 1 H = 4 H = 4 O = `2` O = `4`

$ \boxed{CH_4 + 2O_2 \ \rightarrow \ CO_2 + 2 H_2O } $ C = 1 C = 1 H = 4 H = 4 O = 4 O = 4 now it's balanced.

In the future, you can use this site to check your work too: https://www.webqc.org/balance.php You can even do stoichiometry by changing the moles, masses, and even find the limiting reagent. In general webqc.org has great chemistry tools.
