How does the electrolysis of water produce hydrogen gas? A) Hydrogen cations give electrons to the anode through reduction reactions.
B) Hydrogen cations give electrons to the anode through oxidation reactions.
C) Electrons from the cathode combine with hydrogen cations through reduction reactions.
D) Electrons from the cathode combine with hydrogen cations through oxidation reactions.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
