In the fire tetrahedron, what is the reducing agent?

Explanation:
The reducing agent is the fuel. In combustion, the substance that gets oxidized (loses electrons) is the fuel, while the substance it reacts with to gain those electrons is the oxidizer, which is oxygen. Heat and the chemical chain reactions are important for starting and maintaining the flame, but they are not the chemical participants that are oxidized or reduced. The fire tetrahedron includes heat, fuel, oxygen, and the chemical chain reactions; removing any one of them stops the fire, and among the four, the reducing agent role is played by the fuel because it undergoes oxidation during burning.
