Write the type of heat of combustion.
Types of the heat of combustion:
(1) Complete combustion: This combustion occurs in an unlimited supply of air, oxygen in particular.
(2) Incomplete combustion: It takes place when the air is in limited supply.
(3) Rapid combustion: Rapid energy needs external heat energy for the reaction to occur.
(4) Spontaneous combustion: This means that it requires no external energy for combustion to start.
(5) Explosive combustion: It happens when the reaction occurs very rapidly.
