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!
