3 points A group of friends decides to have a bonfire on Friday night. They luckily
have the fire to keep them warm and allow them to see each other at
night. As the firewood burns, they notice that ash is forming on the
ground beneath the log. They have been learning about chemical
reactions in school and begin discussing if the fire is a chemical reaction.
Has a chemical reaction taken place? Thoroughly justify with at least two
pieces of evidence.
