Many metals react with halogens to give metal halides. For example,
2 Al (s) + 3 Cl2(g) ? 2 AlCl3 (s)
If you begin with 13.5 g of aluminum:
A) you will need 23.6 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.
B) you will need 53.2 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.
C) you will need 26.6 g Cl2 for complete reaction and will produce 49.0 g of AlCl3.
D) you will need 11.8 g Cl2 for complete reaction and will produce 49.0 g of AlCl3.
E) none of the above
