Final answer:
Incomplete combustion in an equation is represented by the product CO (carbon monoxide).
Step-by-step explanation:
The product in an equation that shows incomplete combustion is CO (carbon monoxide).
Incomplete combustion occurs when there is not enough oxygen available to completely burn a fuel. Instead of forming carbon dioxide (CO2) or water (H2O), carbon monoxide (CO) is produced.
This can be represented in an equation such as:
2C3H8 + 7O2 → 2CO + 8H2O
