What is an example of a chemical reaction Water boiling nails rusting sugar dissolving wax melting?
all of them
What are irreversible materials?
melting choalate,melting ice ,dissolving salt in water
Is an ice lolly melting reversible or irreversible?
Yes it is reversible.
Why is melting a physical property of the wax but flammability in a chemical property?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
Is candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
Is candle wax melting a irreversible change?
areversible action produces new material
What type of reaction occurs when a candle is burned?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
Is melting sometimes irreversible?
It depends on what ur melting

Whay is melting physical proreties of wax but frammabillty is a change propeties?
Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).

no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
What kind of reaction is burning?
Its irreversible and an oxidising reaction
Why is melting wax a physical properties of flammability is a chemical property?
Melting is a physical property because the chemical composition remain unchanged.Flammability is a chemical property because involve a combustion reaction.
