A rubber band is not a compound, it is a mixture; it is formed from rubber and some additives.
Barium melts at 725°C. physical or chemical property
Burning rubber is slang for spinning the tires. The rubber burns due to friction which causes heat which melts the rubber and causes it to smoke.
No. It is water before it melts and it is water after it melts, so melting water is a physical thing, not chemical.
the chemical composition does not change.
The chemical structure is unchanged.
It stabilises it, If it is not vulcanised it melts like chewing gum.
Rubber is an organic material.
It is a physical change. There is no chemical reaction whatsoever.
If the question is in regard to the chemical symbol of rubber, rubber does not have a chemical symbol. This is because rubber is a chemical compound rather than a single chemical element. Many rubber compounds are hydrocarbons (composed of carbon and hydrogen), and there are many, many different rubber compounds. A general division of rubbers is that between natural rubber and synthetic rubber, and these have been developed over years to suit a wide variety of applications.
it is a chemical change
Glass melts all the time.
according to chemical structure of rubber
Chemical Change!Because when chocolate start out as just chocolate but when it melts it becomes a chemical because its just something to drink like water,Water is a chemical beause its just something to drink,but you don't actuly drink chocolate,it just becomes a chemical because it melts in to a liquid and all liquids are just becomes a solid,so Chocolate is a chemical when it melts because its just like water but chocolate isn't water its just like water because it melts into a chemical!
the chemical reaction is egg6786
Rubber is not a change of any sort. It is a mixture of organic polymers that can undergo physical and chemical changes.
Melting butter is a physical change, not a chemical change.
Melting is not a chemical change because the chemical formula of water remain unchanged.
i believe physical
