chemical reaction

n
(Chemistry) a process that involves changes in the structure and energy content of atoms, molecules, or ions but not their nuclei. Compare nuclear reaction

Our impulses are not patent to a casual observation, but are only to be discovered by a scientific study of our actions, in the course of which we must regard ourselves as objectively as we should the motions of the planets or the chemical reactions of a new element.
We do not say so, because we can account for the behaviour of water by the laws of physics; and if we knew more about animals, we might equally cease to attribute desires to them, since we might find physical and chemical reactions sufficient to account for their behaviour.
