Question

What is the chemical equation for solid aluminum reacts w/ solid iodine to produce solid aluminum iodide?

Answer 1

How would you use the subscripts?

Answer 2

This is not ideal but we do this.
2Al(s) + 3I2(s) ==> 2AlI3(s)

Answer 3

2Al (s)+ 3I2 (s) >>> 2AlI3 (s) is the normal way we do it. It means this
2Al (s) + 3I₂ (s)>>2AlI₃

Answer 4

and add the (s) after the aluminum iodide, I forgot.
