Which observation would be most likely to happen if a power supply were added to the electrochemical cell? A)Magnesium would be oxidized.
B)Electrons would flow through the salt bridge.
C)The Al electrode would become neutral.
D)The Mg electrode would become the cathode.

12. complete each of the following word equations for synthesis reactions. a. sodium + oxygen -> b. magnesium + fluorine -> 13. complete and balance the equations for the decomposition reactions. a. hgo -> [with the triangle heat symbol above the arrow] b. h2o(l) -> [with "electricity" written above the arrow]

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.
