Question

Which one of the following substances is the product of this combination reaction? Al (s) + I2 (s) → ________(A) AlI2(B) AlI(C) AlI3(D) Al2I3(E) Al3I2

Answer 1

`AlI_3`

Step-by-step explanation:

Combination reactions are the reactions in which two or more atoms/ molecules combine to give a single product.

Aluminum metal combines with iodine to given aluminium iodide.

Aluminium has a valency of 3 and iodine has valency of 1, so the formula is
`AlI_3`

The reaction is shown below as:

`Al_((s))+I_2_((s))\rightarrow AlI_3_((s))`
