This is an oxidation-reduction (redox) reaction:

6 C-II - 24 e- → 6 CII (oxidation)

12 O0 + 24 e- → 12 O-II (reduction)

C6H12 is a reducing agent, O2 is an oxidizing agent.

### Word equation

cyclohexane + oxygen → carbon monoxide + water

### Input interpretation

C6H12 + O2 → CO + H2O

Cyclohexane oxygen carbon monoxide water

### Balanced equation

Balance the chemical equation algebraically:

C6H12 + O2 → CO + H2O

Add stoichiometric coefficients, c1, to the reactants and products:

c1C6H12 + c2 O2 → c3 CO + c4 H2O

Set the number of atoms in the reactants equal to the number of atoms in the products for C, H and O:

C: 6c1 = c3

H: 12c1 = 2c4

O: 2c2 = c3 + c4

Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c1 = 1 and solve the system of equations for the remaining coefficients:

c1 = 1

c2=6

c3=6

c4=6

Substitute the coefficients into the chemical reaction to obtain the balanced
