Answer:
0.0522 mol NaSo4
Explanation:
3.148 x 10^22 Formula units NaSo4 * 1 mol NaSo4 / 6.02 x 10^23 Formula units NaSo4 = 0.0522 mol NaSo4
Yes. If this is the balanced equation:
AlCl3 + 3Na —— 3NaCl + Al
then Al was reduced from a 3+ oxidation (to neutralize the 3- from the chlorine) to a 0 oxidation (elemental ground state).
