uh never mind that makes no sence

Answer 5

For example when wood burns, it must do so in the presence of O2 and a lot of heat is produced: Wood as well as many common items that combust are organic (i.e., they are made up of carbon, hydrogen and oxygen). When organic molecules combust the reaction products are carbon dioxide and water (as well as heat).
