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

What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
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.
Is mixing powdered sugar and iodine a chemical change?
Mixing powdered sugar and iodine is a physical change, not a chemical change. In this case, the substances are simply being combined physically, without any new substances being formed. A chemical change would involve a reaction between the powdered sugar and iodine, resulting in the formation of new substances with different chemical properties.
What do you call the energy which is stored in chemical fuels such as petrol?
The energy stored in chemical fuels such as petrol is called chemical potential energy. This energy is released when the fuel undergoes a chemical reaction, such as combustion, which can be harnessed to do work.
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 a change that makes new substances?
Chemical
What do you call a mixture that produces a chemical reaction?
A mixture that produces a chemical reaction, scientifically speaking, is a chemical change.
What do you call the chemical change of solid and gas?
The PHASE change of solid TO gas is called Sublimation.
Can you call a chemical reaction a chemical change?
They are just two different terms that mean the same thing.
What do you call the new substance that forms from a chemical change?
The substance formed in a chemical change is called Product.
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.
What do you call a change that produces new materials with new properties?
umm....CHEMICAL change..! 0.o
What do you call the change of one chemical element into another through nuclear reaction?
answer TRANSMUTATION
What is a chemical chage?
a chamical change is when something like your butt explodes into many pieces and you can't glue it back. it is also when you can't poo for seventeen years. thank you come again, no refunds , no checks. we will give free advertisement. must be 18 or older to call. now goodbye
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.
What do we call the substances present before a chemical change?
The substances present before a chemical change are called reactants. They undergo a transformation during the chemical reaction to form new substances known as products. Reactants are crucial in determining the outcome of the reaction based on their chemical properties and interactions.
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.
