Question

Balance the following reaction. A coefficient of "1" is understood. Choose option "blank" for the correct answer if the coefficient is "1."
CH3OH + O2 → CO2 + H2O

Answer 1

2CH3OH+302  -->  2C02+4H2O

Answer 2

Balanced chemical reaction:

1) CH₃OH + 3/2O₂ → CO₂ + 2H₂O or

2) 2CH₃OH + 3O₂ → 2CO₂ + 4H₂O.

Number of atoms must be the same on left and right side of balanced chemical reaction according to the law of conservation of mass or principle of mass conservation.

1) There are four hydrogen atoms, one carbon atom, four oxygen atoms in this chemical reaction.

2) There are eight hydrogen atoms, two carbon atoms, eight oxygen atoms in this chemical reaction.
