A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.
Because oxygen and hydrogen molecules combine to make h2o meaning water and it cannot be seperated again.THATS THE FINAL ANSWER.
No, the process can be reversed by electrolysis,.
The changes produced by electrolysis are chemical.
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
Irreversible chemical change.
burning or tree or wood is an irreversible chemical change.
because it is irreversible and it has a new substance
Electrolysis is a chemical change.
Chemical science, because yeast is irreversible. Chemical Change: Irreversible Physical Change: Reversible
The changes produced by electrolysis are chemical.
its a chemical change beacuse it is irreversible :)
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
Irreversible chemical change.
Chemical because it breaks apart the individual compounds on the molecular scale.
Yes, but it is so hard as not to be worth it.
a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
Physical
A fire is a chemical change due to the irreversible changes that happen.
