Study the chemical reaction below and answer the questions that follow: 8Al + 3Fe₃O₄ → 4Al₂O₃ + 9Fe How many moles of iron would be produced if 4.0 moles of aluminum reacts with an excess of Fe₃O₄? A. 4.0 moles
B. 4.5 moles
C. 8.0 moles
D. 9.0 moles

the answewr is A. hope this helps!

Explanation:

C. A few alpha particles bounced back during the scattering experiment.

Explanation:

Rutherford's gold foil experiment proved that the center of the atom is dense which caused some of the alpha particles to bounce back. This proved that most of the mass of the atom is located at the center, however, the rest of the atom is empty. It also showed that the center of the atom stores all the positive charges.
