Gaseous methanol (CH4O) reacts with oxygen gas to produce carbon dioxide gas and liquid water. Balanced the equation using the lowest possible whole numbers. What is the sum of the coefficients in the balanced equation?

The sum of the coefficients in the balanced equation is 11

Explanation:

A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.

The balance reaction of combustion for methanol is:

2CH₃OH (l) + 3O₂(g) →  2CO₂(g)  +  4H₂O (g)

Coefficients from stoichiometry are 2, 3, 2 and 4

Sum =  2 + 3 + 2 + 4 = 11
