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 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.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Is sublimation a physical change or physical property?
Sublimation is a physical change, as it involves a substance transitioning directly from a solid to a gas without passing through the liquid phase. It is not a physical property, but a phenomenon observed in specific substances under certain conditions.
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.
Why is sublimation of ammonium chloride is both physical and chemical change?
Sublimation of ammonium chloride is considered a physical change because it involves a phase transition from a solid to a gas without any change in the chemical composition of the substance. However, it can also be considered a chemical change because the bonds holding the ammonium chloride together in the solid phase must be broken in order for sublimation to occur, resulting in the separation of ammonium ions and chloride ions.
Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
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 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.
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 sublimation a physical change?
Sublimation is a physical change.
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.
