Concept: The Conservation of Matter

# Problem: When a small log completely burns in a campfire, the mass of the ash is much less than the mass of the log.What happens to the matter that composed the log?

###### FREE Expert Solution

We’re asked to determine what happens to the matter that composed the log that burns.

We know that when a small log completely burns in a campfire:

• mass of the ash is much less than the mass of the log.

Recall that according to the Law of conservation of massmatter is not created or destroyed:

This means that:

mass of reactants = mass of product

mass unburned log + mass of oxygen, O2 (used to burn the log) = mass of ash

reactants                                                             products
