Is sublimation of ammonium chloride a physical change or a chemical change?
JakePhoenix
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 of sodium chloride chemical or physical change?
Sublimation is a physical change.
Is subliming ice a chemical change?
No, sublimation is a change of state, so it is a physical process.
Is sodium chloride a chemical or physical property?
Sodium chloride is a chemical compound (NaCl), not a property.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
Is sublimation a physical change or physical property?
Sublimation is the physical change of a solid to a gas skipping the step of becoming a liquid. This is a physical change because you haven't changed the chemical nature of the substance. Think of when you take ice out of the freezer and you see "smoke" coming off of it. That is sublimation. The rapid change in temp caused the solid ice to skip its liquid stage and go straight to its gaseous stage
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Does ammonium chloride and water is a chemical or a physical change?
Dissolution is a chemical process.
Is heating ammonium chloride crystal a physical or chemical change?
yes
Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
Is dissolving ammonium chloride in water a chemical change?
No. The ammonium chloride is diluted by the water, so it's not as concentrated as before. The only time that it will be a chemical change will be when the ammonium chloride reacts with water, that is, IF it reacts with water.
Is sublimation a chemical or physical?
Physical
Is ammonium chloride a sublime substance?
Ammonium chloride is a solid formed when two gasses (NH3(g) and HCl(g) ) are put together. (--> NH4Cl(s) )It may be called 'chemical sublimation', though literally speaking this is a 'contradictio in terminis'.This looks like a solid cloudy smoke coming out of gas, very much the same as the pure physical sublimation of iodine gas to iodine crystals or the formation of hoar-frost (ice from humid freezing air)
Is subliming ice a chemical change?
No, sublimation is a change of state, so it is a physical process.
Is sodium chloride a chemical or physical property?
Sodium chloride is a chemical compound (NaCl), not a property.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
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 sublime a physical change or chemical change?
Subliming (better known as sublimation) is a change in state, so it is a physical change.
