Most chemical changes are _________ and cannot be reversed .
Pachacha [2.7K]

Answer:

irreversible changes

Explanation:

Most chemical changes are permanent and cannot be reversed. That is because a chemical change involves changing the molecular composition which can't be reversed. A common example of a chemical change would be burning wood. The wood burning into ash is changing the molecular composition of the wood transforming it to ash. Now can ash be changed back into wood? No, it is a "irreversible change."

Hope this helps.
