yes
Yes. It's just like ice to water and back to ice. - - - - - "Reaction" implies a chemical change. Melting chocolate is a physical change. (Hardening melted chocolate can involve a whole series of physical changes but that's a different issue.)
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
You think probable to a reversible reaction.
No, you can take the melted chocolate goo and pour it into a mold, cool it and re-form the candy bar. No, melting a chocolate bar is not an irreversible change. Melting a chocolate bar is just changing its state of matter. If you but the melted chocolate bar in a freezer, where exothermic processes will occur, and the chocolate bar will be solid again.
no, you cannot get cheese back to cheese when melted
chocolate is reversible when you melt it put it in the freezer but if you eat it it will not be reversible
An anabolic reaction is considered reversible.
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
Reversible Reaction
yes!
A chemical reaction in which the products re-form the original reactants is called a reversible reaction.
