The claims which are supported are :

A. Matter is conserved during the burning of wood.

C. Burning wood involves a series of chemical reactions that occur in one direction only.

E. Burning wood involves oxygen as well as carbon.​

Explanation:

  • Burning of wood involves wood reaction with oxygen in which carbon dioxide is released.
  • When wood is heated, it results in production of a substance that reacts easily with oxygen leading to ignition of wood and its burning.
  • Burning of wood is a type of thermal decomposition.
  • Burning of wood releases energy in the form of heat.
  • Once wood is burned it can not be reacted or changed back to wood. So, this reaction is considered as irreversible reaction, that occurs only in one direction.
  • Matter is conserved during the burning of wood as a chemical reaction does not result in creation or destruction of matter.
