- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Dry ice sublimates fastest in iodine due to the interaction between the two substances. Iodine has a relatively low boiling point and can create a higher local vapor pressure, facilitating the transition of dry ice from solid to gas. Additionally, the presence of iodine can lower the sublimation point of dry ice, enhancing the sublimation process. This combination of factors leads to accelerated sublimation rates in the presence of iodine.
If zinc chloride is heated strongly the solid will sublime.
Sublimation is the process of direct transformation of a solid in a gas: examples are iodine, naphthalene, dry ice, camphor.
iodine
Yes, the sublimation of iodine is a physical change, not a chemical change. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. The chemical composition of iodine remains the same during sublimation.
it's called sublimation

It is a physical change (sublimation).
Yes, the sublimation of iodine is a physical change. Sublimation is the process by which a substance transitions directly from a solid to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Heating iodine sublimation occur: this is a direct change from solid to gas.
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
it is a physical change , sublimation is a transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. the iodine crystals when subject to heat turns to a violet gas , and when it cools it turns back to solid form. the composition doesn't change so it n is only a physical change
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.
It is called sublimation
The chemical equation for the sublimation of iodine solid to iodine gas is: I2(s) -> I2(g). This represents the process in which solid iodine directly transforms into iodine gas without going through a liquid phase.
