Yes, combustion is simply the chemical reaction of a substance with oxygen molecules. In this case the match and match head are reacting with the ocygen int he air.

Why higher density air is better for combustion?
The higher the air density, the more oxygen available for combustion.
Does central air conditioning need combustion air the way a furnace does?
If your referring to the cooling portion of your central air conditioning the answer is no.
The process of burning commonly used to dispose of trash?
There are a few methods of combusting trash. Open grates, and fluidized combustion beds are the most prominent. Both methods use a starter fuel and High air flows to accomplish complete combustion.
Why can you feel a match burn when you put your hand above but when it's underneath you can't?
Hot air rises.
Why are chimney's placed above the roof of a house?
Because the gases formed by combustion are lighter than air, so creating an updraft
Why is it important to light the match before opening the gas tap when lighting a Bunsen burner?
Because gas will escape into the air, making more dangerous air, so if you light the match with all the gas in the air, a tiny explosion will occur
How does the lighting of a match become possible?
Because of friction between match stick and box because of presence of oxygen in air
How can incomplete combustion occur in a gas boiler?
Incomplete combustion inevitably occurs when fuel is burned with insufficient oxygen. In the case of gas appliances this can occur if the system for mixing fuel and air is incorrectly set or if the flow of air to the appliance is inadequate.
What gas in the air reacts with oil as it burns?
As with most other fuels, oxygen gas is required for the combustion of oil to occur.
Why the candle stays alight even when you take the match away?
Because the combustion (oxidation, reaction with oxygen) continue as long as there is air available.
Why is it so important for the ignition process to occur in a gasoline car?
For a combustion engine to work, it must have the following: Air Fuel Ignition if any of the above are not present, combustion cannot take place.
Why does lightning and thunder occur everywhere?
Because of the clouds. When Cloud's get to full they ran and warm air help's that to make lighting.
Why you blow on a match it put it out?
Any extinguishment of fire is caused by removal of one or more parts of the fire tetrahedron: Oxygen, Heat, Fuel, & Chemical Reaction. In the case of blowing out a match you are removing HEAT. You are disrupting the area of heat being caused by the match and by blowing more air onto it, you are in fact displacing the heat. Sustained combustion must occur at certain temperatures depending on the fuel and level of oxygen, thus blowing air at a fast rate onto the match causes the temperature to drop below this temperature and go out.
What causes ignition to occur in a diesel engine?
When the piston compresses the fuel-air mixture, the spark ignites it, causing combustion
Does air support combustion?
Yes, combustion requires oxygen which is found in air.
What is humming in gas turbine?
The formation of combustion oscillations can occur during an operation of a gas turbine burner. This is also known under the concepts of "combustion chamber humming", "combustion chamber oscillations", "combustion-induced pressure pulsations", "oscillating combustion processes". The combustion oscillations are due to an interaction between the quantity supplied per unit time of combustion air/fuel mixture flowing in the flow duct of the burner. The mixture is ignited after entry into a combustion chamber and burns in a flame, with the momentary combustion conversion in the flame. Combustion conversion designates the quantity of combustion air/fuel mixture converted per unit time during a combustion process in a flame. Pressure fluctuations in the combustion chamber, which can lead to the formation of a stable pressure oscillation, can occur due to a change in the combustion conversion. In addition to an increased production of noise, the combustion oscillations cause an increased mechanical and thermal load on walls associated with the combustion chamber and on other parts belonging to the combustion system.

Why excess air is provided for combustion?
To ensure complete combustion of the fuel used, combustion chambers are supplied with excess air. Excess air increase the amount of oxygen and the probability of combustion of all fuel
