Apr 8, Related questions How does a balanced equation illustrate the Law of Conservation of Mass? Question 42aa4. Why is the law of conservation of mass important for balancing equations? How does the mass before a reaction compare to the mass after a reaction according to the law of Why is conservation of mass a law? The Law is also applicable to both chemical and physical changes.
For example, if you have an ice cube that melts into a liquid and you heat that liquid up, it becomes a gas. It will appear to have disappeared, but is still there.

Binod Shrestha University of Lorraine. The flames are caused as a result of a fuel undergoing combustion burning. Law of Conservation of Mass The law of conservation of mass was created in by a French chemist, Antoine Lavoisier.
Answer Summary Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur.
Because a log is made of wood and wood is made of cellulose, a carbohydrate, we can assume the change in mass comes from the CO2 formed and the water that evaporates.
Some went up the flue, some are in the ashes, some entered the room you might have breathed some of those. They are all still somewhere. No, what is left of the log is reduced in mass but mass is conserved as the remainder is ashes and tiny particles that rise as smoke,. The ashes of Yule logs were meant to be very good for plants.
This is true, because the ash from burnt wood contains a lot of 'potash,' which helps plants flower. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log 0. Log in. Study now.
