Can a chemical change be undone?
Some chemical changes are reversible, others are not.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
What is the Harmful effects of chemical change?
Chemical changes can lead to the release of toxic fumes, the creation of hazardous byproducts, and the potential for fires or explosions. Additionally, some chemical changes can result in environmental pollution or damage to ecosystems.
Why is Wood burns to form black charcoal a chemical change?
It changes properties.Physical Changes:Physical changes are changes in the appearance but not in the chemical properties. Some physical changes can be undone so the item can be put back to almost its past form.Chemical Changes:Chemical changes are the changes in chemical properties. Chemical changes also change in appearance and/or leave behind traces to prove that a chemical change occurred. Chemical changes create a new substance when they happen, e.g., cooking an egg. Chemical changes cannot be undone as the molecules, patterns and properties have been changed.How to tell them apart:The way to tell the difference between chemical and physical changes is by the changes that it went through. There may be clues that a chemical change appeared because of sound, light, gas production or an odour. A physical change does not involve any of these.
What are some harmful chemical changes in our daily life?
Some harmful chemical changes in daily life include exposure to air pollutants such as carbon monoxide and lead, ingestion of toxins in food and water, and exposure to harmful chemicals in cleaning products and cosmetics. These chemical changes can have adverse effects on our health and well-being.

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.

What are some useful chemical change?
Some useful chemical changes are when a solid changes into a liquid. Such as when ice melts it is turned into water.Sorry but I am afraid that is wrong.Freezing, melting and evaporation including sublimation, i.e., Changes of State, are all physical, not chemical, changes.As for "useful" chemical changes.... Almost all biological processes, the conversion of fuel to its oxides etc with consequent release of heat &/or light, the list goes on!
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
