A new compound must be obtained.
No. It is a chemical change. By the way, burning something is a chemical change only.
No, chemical change is the only way.
The only way to be sure a chemical reaction or change has occurred is to test the composition of a sample before and after a change.
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.

Chemical changes alter the chemical makeup of a substance... physical changes only change the way something looks, it does not modify the chemical properties.
The only way to break down a compound is through chemical change. sometimes, energy is needed for a chemical change to happen. 8thGrader,(:
Le Chatelier, H L 1850-1936. Scientific Law Description; If a system in chemical equilibruim is subjected to a disturbance it tends to change in a way which opposes the disturbance.

This is a physical change because the things that make up the platinum have not been changed, but the appearance has changed.
