The law of reflection states that, when a light ray strikes a reflecting surface, the angle of incidence (measured from the normal line) is equal to the angle of reflection (also measured from the normal line).

Electrolytes may be covalent compounds that chemically react with water to produce ions (for example, acids and bases), or they may be ionic compounds that dissociate to yield their constituent cations and anions, when dissolved. Dissolution of an ionic compound is facilitated by ion-dipole attractions between the ions of the compound and the polar water molecules.

Saturn is the only planet in the Solar System that would float on water (given a large enough ocean). If the star is large enough, gravity can be strong enough to push the electrons of the atoms into the nucleus, forming a “neutron star”, which is essentially a giant ball of neutrons.
