CH4+4O2→CO2+H2O (plus heat!)
What happens chemically when wood burns?
Wood is made of fiber (cellulose) and minerals (metals). When wood is burned, oxygen and other elements in the air (mainly carbon, hydrogen and oxygen) react to form carbon dioxide that is released into the atmosphere, while the minerals turn into ashes. … Thus the carbon is left to turn into charcoal.
What kind of reaction is burning wood?
An exergonic reaction (burning wood) produces energy (heat) which is taken up and used to make an endergonic reaction (cooking the egg) take place. Energy is transferred from one type of reaction to another.
What is fire formula?
As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy.
What is the basic chemistry of fire?
Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different.
What is wood chemical formula?
Cellulose is a natural polymer, a polysaccharide with a long chain molecule. The cellulose formula (C6H10O5) n, where n is the degree of polymerization, is 6000-14000.
What is the chemical potential energy of wood?
Burning wood is an exothermic reaction which turns the chemical potential energy stored in the cellulose into heat energy (and light). The most notable changes are the release of heat to the surroundings and the breakdown of the wood to form water vapor and carbon dioxide.
What gases are released by burning wood?
Woodburning Pollutants
- Carbon Monoxide (CO) …
- Carbon Dioxide (CO2) …

- Indoor Air Pollutants of Concern.
Is there any chemical formula of fire?
Fire is not a chemical, so does not have a formula… You might be after the requirements for burning, in which case those are fuel + oxygen + heat.

What is chemical chain reaction in fire?
A fire is an example of a chemical chain reaction. A chemical chain reaction is a series of chemical reactions where the products of the reaction contribute to the reactants of another reaction. This transformation of products to reactants allows a reaction to continue with minimal or no outside influence.
What is the chemistry and physics of fire?
Fires usually receive oxygen, which combines with the fuel in the combustion process, from the surrounding air. Mixtures of fuel gas and air will burn only if their composition rests within certain limits. Smoke, the visible product of a fire, serves also as a warning of the presence of toxic gases.
