Both are true .. since in chemical reaction it involves change in state of matter (all though physical state could be reversed again for ex - when phenolphthalein reacts with base it turns pink and become colourless after sometimes ) as well as interaction between the atoms of the elements. Water gets decompose to produce Hygrogen and oxygen gas during electrolysis .
