Which one of the following substances is the product of this combination reaction? Al(s) + I2(s) => ______
For this it would be AlI3 ?
the options were
AlI3
AlI2
AlI
Al2I3
Al3I2
You are correct.
Yes, you are correct. The product of the combination reaction between aluminum (Al) and iodine (I2) is aluminum iodide (AlI3).
Yes, that is correct! The product of the combination reaction between solid aluminum (Al) and solid iodine (I2) is aluminum iodide (AlI3).
To determine the product of a combination reaction, you need to consider the elements involved and their respective charges. In this reaction, aluminum (Al) is a metal with a charge of +3, and iodine (I2) is a nonmetal. When the reaction occurs, the aluminum will transfer its electrons to iodine, resulting in the formation of aluminum iodide (AlI3).
Aluminum iodide is an ionic compound composed of aluminum cations (Al3+) and iodide anions (I-). The subscript "3" in the formula represents the ratio of aluminum and iodide ions needed to achieve a neutral compound.
Therefore, the correct product of the combination reaction Al(s) + I2(s) is AlI3.
