When a conductor is passed through a magnetic field, a current is induced in the conductor. This phenomenon is called electromagnetic induction. A changing magnetic field creates an electric field or current. This happens because of the movement of electrons in conductor as affected by the presence of the changing magnetic field.
3)
It has more surface area to react with
Molar mass of A l 2 (S O 4 ) 3 = 342.15 g/mol
7.2g/ 342.15 g/mol
you can get number of moles.
then multiply that by12
Answer:
That's not true. It would in fact be physical.
Explanation:
physical change: some of its physical properties may change but its identity does not
