To Answer your question, it can be reversed, but it not so easy.
Look at what I found in an article:
"Physical changes, like the melting of a solid to a liquid can be reversed easily - just refreeze it.
Chemical changes, like the blackening of toast when burnt, are not so easy to reverse."
Hope I Helped

∙ 13y agoWhen you bake a cake the cake goes from liquid to solid changing chemically. Now try to imagine unbaking that same cake. It's hard to reverse a chemical change because a new substance is formed in that change
Wiki User
∙ 9y agoA chemical change is a change that cannot be undone. A chemical change cannot be reversed because a new substance will be formed.

∙ 13y agowell.... it is called "irriversible process".... that's what my friend says....if you wish you can call it "unidirectional process" or a "chemical change".
Wiki User
∙ 13y agoIt is called an irreversible change. that's a big word so be careful.

The change the colour of something especially by using a special liquid?
Of course you can. That is what you call "chemical change". Put indicator fluid in water. You'lle see what I'm talking about.
Is wool forming on sheep a chemical change or a physical change?
Let's call it a biological change. It has elements of both physical and chemical, but wool doesn't "form" on a sheep like, say, mold on a loaf of bread; wool is sheep hair and it grows out of hair follicles all over the animal.
What do you call the energy which is stored in chemical fuels such as petrol?

What should you do if someone has ingested a hazardous chemical?
Call 911 or Poison Control or your local emergency number immediately. If you are able to find the container that the chemical came from, have it with you when you call. Read it to see if it says to give the person milk or water or anything else. If it does, give the person what it says to give them. If it doesn't say to give them anything, DO NOT give them anything. When the person from 911 or Poison Control answers the phone, read them the name of the chemical. Spell it if you cannot pronounce it. Do what the person from 911 or Poison Control says to do.
What do you call a short representation of a chemical reaction?
A short representation of a chemical reaction would be the net ionic equation.
What do you call the new substance that forms from a chemical change?
The substance formed in a chemical change is called Product.
What do you call a change that makes new substances?
Chemical
Why is the candle burning a chemical change?
It is a chemical change because inside the stove the Kerosene gets burnt and produces flames and energy in the form of heat and light. We cannot get back Kerosene again from the products of is combustion. Hence, we call the combustion of Kerosene as a Chemical Change.
Is ability to react with other substances chemical or physical?
This is a chemical reaction. When substances change you can call it chemical.

They are just two different terms that mean the same thing.

Is the conversion of two compounds into a solution a chemical change?
Not necessarily. There's something called the enthalpy of mixing which can be responsible for lowering the temperature when two substances are mixed even if no chemical reaction occurs. It may also be an endothermic reaction; if there are other signs of a reaction (formation of a precipitate, evolution of a gas, color change, etc.) then it probably is a chemical reaction.
What does the law of conservation of mass state that cannot be created or destroyed during a chemical reaction?
The law of conservation of mass (or matter) states that mass (or matter) cannot be created or destroyed during a chemical reaction. *Matter is anything that has mass and takes up space, so a lot of scientists call this the law of conservation of matter.
