Question

Balance the chemical reaction for the combustion of methanol by adding the correct coefficients below

__CH3OH +__O2(little box)__CO2 +__H2O

Answer 1

`2~CH_3OH+3~O_2\rightarrow2~CO_2+4~H_2O\\`

The coefficients would be 2, 3, 2, and 4.

Step-by-step explanation:

If we want to check this we would multiply the coefficient by each element. What we want is to have the same number of atoms on each side.

Reactant side:

• # of carbon atoms: 2
• # of hydrogen atoms: 8
• # of oxygen atoms: 8

Product side:

• # of carbon atoms: 2
• # of hydrogen atoms: 8
• # of oxygen atoms: 8

And that's it!
