Balance the chemical equation given below,and determine the number of moles of iodine that reacts with 10.0 g of aluminum. ________ Al(s)+ ________ I₂(s)→ ________ Al₂I₆(s)

Question

Quizplus · Accepted Answer

The balanced chemical equation is:

2Al(s) + 3I2(s) → 2AlI3(s)

From the equation, we can see that 3 moles of iodine react with 2 moles of aluminum. Therefore, we need to first convert the mass of aluminum to moles:

moles of aluminum = mass/molar mass = 10.0g/26.98g/mol = 0.371 mol

Now we can use mole ratio to determine how many moles of iodine is required:

moles of iodine = (3/2) x moles of aluminum = (3/2) x 0.371 mol = 0.556 mol

Therefore, the answer is B) 0.556 mol.
