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!

There are no useful ones on the list that follows the question.
As we age, our bodies go through certain changes. We live in a harsh environment here on the Earth. Some symptoms of aging can be attributed to environmental factors such as exposure to radiation from the sun, air pollution and chemicals in the food and water which we ingest. Still others involve oxidation of the molecules of our bodies by harmful 'free radicals' which do damage to our DNA. The list goes on, I'm sure. The biggest factor is our lifestyle. Our diet, activity level and harmful chemicals we choose to indulge (alcohol, tobacco, drugs).
A linked list is useful for data which will be changed very often. The linked nature of linked lists makes them ideal for inserting and removing elements, as it requires only changing one or two pointers.
