📐 Combustion Types — Visual Comparison

Complete combustion (left, blue flame) produces CO₂ and H₂O molecules. Incomplete combustion (right, yellow flame) produces CO and soot carbon particles.

Figure 1: Complete combustion (left) needs plenty of oxygen — products are only CO₂ and H₂O. Incomplete combustion (right) with limited oxygen produces toxic CO and/or soot (C).
