Question

1. in the previous problem, ion charges were used to predict the formula of a product containing aluminum and iodine. write the formulas of the reactants and products for the combination reaction of aluminum with iodine. i need a hint a + b → ab choices: al al₂ al³⁺ i i₂ i⁻ ali₂ ali₃ ali al₃i 0 / submissions used

Explanation:

Step1: Identify reactants

Aluminum is a metal with symbol Al and exists as Al in elemental form. Iodine is a non - metal and exists as $I_2$ in its elemental form.

Step2: Determine product

Aluminum forms a $Al^{3 + }$ ion and iodine forms $I^{-}$ ion. To balance the charges, for every $Al^{3+}$ ion, we need 3 $I^{-}$ ions. So the product is $AlI_3$.

Answer:

Reactants: Al, $I_2$; Product: $AlI_3$
