Most metals are very reactive, as are the elements in the halogen group. aluminum, for instance, for example, reacts with elemental chlorine to form aluminum chloride. if you have a 13.5 g sample of al, which choice below is true?
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 11.8 g cl2 for complete reaction and will produce 49.0 g of alcl3.
d. you will need 26.6 g cl2 for complete reaction and will produce 49.0 g of alcl3. reset selection

 B. you will need 53.2 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

The balanced reaction is:

2 moles of aluminium react with= 3 moles of chlorine

Thus 0.5 moles of aluminium react with=  moles of chlorine

Mass of chlorine=

2 moles of aluminium produce = 2 moles of aluminium chloride

Thus 0.5 moles of aluminium react with=  moles of aluminium chloride

Mass of aluminium chloride=

Thus 53.2 g of chlorine is used and 66.7 g of  aluminium chloride is produced.
