HELP!! The direct transformation of solid iodine to the gaseous state at room temperature?

NetherCraft 0

1. results in a chemical change.

2. results in the reaction I2 ! 2 I.

3. does not affect the density of the iodine.

4. is an endothermic process.

5. is a chemical property of iodine.

1 Answer

  • 4. is an endothermic process.

    (A change of state is not a chemical change; the I2 molecule does not dissociate in this condition; the density does change, a lot, when going from solid to gas; this is a physical, not a chemical, property.)
