From the atmosphere (air) surrounding the wood. The wood would not burn in a vacuum devoid of air. Air is composed of approximately 20% oxygen.

The burning of wood is best described as what?
Burning is a chemical reaction with oxygen, an oxydation.
Why is it that fanning burning wood keeps the wood burning?
Fanning them brings in more oxygen. With more oxygen you get more fire.
Does wood undergo an exothermic reaction or an endothermic reaction?
Like all burning reactions (with oxygen that is) burning wood is also exothermic.
How is respiration similar to burning wood?
As we all know , in respiration we intake oxygen and gives out carbon dioxide, for burning also oxygen is needed. In spite of oxygen wood cant be burned and along with burning, the gas coming out from wood is Carbon-dioxide. Oxygen combines with carbon
Why is wood burning chemical energy?
how chemical energy produce in firewood useful
Where does the oxygen needed for burning wood come from?
Oxygen is part of the mixture of gases we breath. Therefore, burning wood uses the oxygen in the atmosphere.
The burning of wood is best described as what?
Burning is a chemical reaction with oxygen, an oxydation.
Do wood and oxygen combine during burning?
Yes
How is wood used for fuel?
Wood is used for fuel through burning it in air (or Oxygen).
Why is it that fanning burning wood keeps the wood burning?
Fanning them brings in more oxygen. With more oxygen you get more fire.
Does wood undergo an exothermic reaction or an endothermic reaction?
Like all burning reactions (with oxygen that is) burning wood is also exothermic.
When wood burns burns a chemical reacton occurs in which the in wood?
Yes, all burning processes are redox reactions between oxygen and the material that's burning.
How is respiration similar to burning wood?
As we all know , in respiration we intake oxygen and gives out carbon dioxide, for burning also oxygen is needed. In spite of oxygen wood cant be burned and along with burning, the gas coming out from wood is Carbon-dioxide. Oxygen combines with carbon
Scientists name who discovered wood and oxygen combine during burning?
Lavoisier.
Is burning wood for energy better than burning fossil fuels for energy?
No,because the trees are limited and used for oxygen.
Chemical Properties for wood?
Wood burns. So, a chemical property could be that certain chemicals in wood react vigorously with oxygen. Burning is a chemcial change, and reactivity with oxygen is a chemical property.
What is the new substance form in burning of wood?
Wood ash (potash) is the main result of burning wood and potash can be used in the garden as a fertilizer. Also, if wood is slowly burnt (charred?) in a kiln, where oxygen is kept out, charcoal is produced.
