Can a chemical change be undone?
Some chemical changes are reversible, others are not.
Are physical and chemical changes simply reversible and non reversible changes?
Chemical changes create new substances and cannot be reversed.Burning paperLighting a matchMixing sugar and waterPhysical changes do not create new substances and can be reversed.Crushing a canTearing paperChopping wood
How can chemical change be reserved?
Reversible changes are the chemical reactions that can be reversed, however most are non reversible. The ones that can be reversed is because the reaction can flow both ways.
Is a permanent tattoo a chemical change?
Yes it is it's not reversible but physical changes are
Why is burning non reversible?
It changes the chemical composition of the burned object making it kinda hard to reverse
What chemical reactions are reversible?
All physical changes are reversible.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually

what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Are chemical changes reversible?
I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
Differences between physical changes and chemical changes?
Physical changes are reversible changes, such as change of state (boiling, melting etc), chemical changes are when something undergoes a reaction changing it's chemical makeup.
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
How can chemical change be reserved?
Reversible changes are the chemical reactions that can be reversed, however most are non reversible. The ones that can be reversed is because the reaction can flow both ways.
