To balance the equation, we need 3 moles of Iodine for every 4 moles of aluminum, so the coefficient of I₂(s) is 3. To determine the number of moles of iodine that reacts with 30.0 g of aluminum, we first convert the mass of aluminum to moles: 30.0 g Al * (1 mol Al/26.98 g Al) = 1.11 mol Al Since the reaction is 4 moles of Al to 3 moles of Iodine, we can use a proportion to find the number of moles of iodine: 1.11 mol Al * (3 mol I/4 mol Al) = 0.833 mol I So the coefficient of I₂(s) is 3 and the amount of iodine that reacts with 30.0 g of aluminum is 0.833 mol, which is closest to option B - coefficient 3, amount 1.67 mol.
