# Problem: What is the sum of the coefficients in the balanced chemical equation for the combustion of acetone, C3H6O(l), in air?

###### FREE Expert Solution

In a combustion reaction a hydrocarbon reacts with oxygen to produce CO2 and H2O.

To balance: add coefficients so that number of atoms of each element on both sides are equal.

C3H6O(l) + 4O2 (g) → 3CO2 (g) + 3H2O (l)

reactants               products

C  - 3                          C - 1 3

H   - 6                         H - 2 6
