Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
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.
What are the chemical reactions involves in sublimation?
Sublimation, per se, does not involve any chemical reactions. It is simply a physical change of a substance going from a solid to a gas without passing through the liquid phase.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
What is the sublimation of carbon dioxide a chemical property or chemical change?
The sublimation of carbon dioxide is a physical change, not a chemical property or change. Sublimation is the process in which a substance transitions directly from a solid to a gas without going through the liquid phase, and it does not involve any change in the chemical composition of the substance.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
Is sublimation of mothballs physical or chemical change?
Sublimation of mothballs is a physical change. Sublimation is the process of a substance transitioning from a solid directly to a gas without going through a liquid phase. It does not involve a change in the chemical makeup of the substance.
Is disappearance of moth ball a chemical or physical change?
The disappearance of a mothball is considered a physical change. This is because there is no change in the chemical composition of the mothball when it disappears; it simply changes form from a solid into a gas through the process of sublimation.
Is subliming ice a chemical change?
No, subliming ice is a physical change where ice changes from a solid directly into a gas without melting into a liquid first. It is a phase transition process and does not involve any chemical reactions or changes in the chemical composition of the ice.
Is sublimation of ammonium chloride a physical change or a chemical change?
Sublimation of any pure substance such as ammonium chloride by definition is a physical change, because sublimation is defined as passage of substance from the solid to the gas phase without passing through an intermediate liquid phase.
Is sublimation a physical change?
Sublimation is a physical change.
