Is iodine sublimating a chemical change?
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.
Why is sublimation of iodine is a physical process?
Sublimation is a physical process because it involves the direct transition of a substance from solid to gas phase without passing through the liquid phase. In the case of iodine, when it is heated, it directly converts from solid to gas without changing its chemical composition, making it a physical change.
Is sublimation of iodine represents a chemical change?
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.
Is iodine becomes a purple gas a chemical change?
Yes, iodine becoming a purple gas is a physical change, not a chemical change. A chemical change involves the formation of new substances with different chemical properties, whereas in this case, the iodine is just changing its physical state from solid to gas without forming any new substances.
Is iodine a physical property or a chemical property?
Iodine itself is a chemical element with a physical property, as it is a solid at room temperature and has a distinctive purple color. Its chemical properties involve its reactivity with other elements and compounds in chemical reactions.
Is iodine sublimating a chemical change?
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.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Iodine sublimes to iodine vapor is physical or chemical 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.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation of solid iodine into purple vapor is a physical change because the chemical composition of iodine remains the same throughout the process. Only the physical state changes from solid to gas.
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- 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.
Why is sublimation of iodine is a physical process?
Sublimation is a physical process because it involves the direct transition of a substance from solid to gas phase without passing through the liquid phase. In the case of iodine, when it is heated, it directly converts from solid to gas without changing its chemical composition, making it a physical change.
Is sublimation of iodine reversible or irreversible?
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
Is sublimation of iodine represents a chemical change?
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.
Is sublimation a physical change?
Sublimation is a physical change.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
What is iodine crystals sublime to make purple gas physical or chemical change?
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
Is iodine becomes a purple gas a chemical change?
Yes, iodine becoming a purple gas is a physical change, not a chemical change. A chemical change involves the formation of new substances with different chemical properties, whereas in this case, the iodine is just changing its physical state from solid to gas without forming any new substances.
