How do you separate ammonium chloride from a mixture of ammonium chloride and potassium chloride?
To separate ammonium chloride from a mixture of ammonium chloride and potassium chloride, you can use the process of sublimation. Ammonium chloride sublimes at a lower temperature compared to potassium chloride. By heating the mixture, the ammonium chloride will directly change from a solid to a gas, leaving behind the potassium chloride. The resulting gas can be condensed back into solid form for collection.
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.
Which type of chemical reaction takes place when barium hydroxide and ammonium chloride are mixed together in terms of heat released or absorbed?
The chemical reaction between barium hydroxide and ammonium chloride to form barium chloride, ammonia and water is characterised by a change in temperature (which is fall in temperature). It is a endothermic reaction (which means heat absorbing reaction). Ba(OH)2 + NH4Cl ------------> BaCl2 + NH3 + H2O
Is heating ammonium chloride crystal a physical or chemical change?
Heating ammonium chloride crystal is a physical change, as it only involves a change in state from a solid to a gas without forming any new substances.
How to separate a mixture of sodium chloride and ammonium chloride?
Sodium chloride and ammonium chloride can be separated either by sublimation or filtration or crystallization. Sublimation can be found on this site ------------ http://www.lenntech.com/Chemistry/sublimation.htm. I personally think that this method is the easiest.

What happens if you mix ammonium chloride with sodium chloride?
no change
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 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.
Does ammonium chloride and water is a chemical or a physical change?
Dissolution is a chemical process.
What is one property which is shown by ammonium chloride but not by sodium chloride?
Ammonium chloride can undergo sublimation, meaning it can change from a solid directly to a gas without passing through a liquid state. Sodium chloride does not exhibit sublimation behavior.
How can you separate a mixture of naphthalene and ammonium chloride?
One way is to slurry the solid mixture with water. The ammonium chloride will dissolve and the naphthalene will not. Ammonium chloride can then be recovered by evaporating the water solution of it that is formed.
How do you determine integral heat of solution of ammonium chloride by the calorimeteric method?
To determine the integral heat of solution of ammonium chloride by the calorimetric method, you would dissolve a known mass of ammonium chloride in a known volume of water in a calorimeter. Measure the temperature change that occurs during the dissolution process to calculate the heat absorbed or released. Use the formula q = mcΔT, where q is the heat, m is the mass of the solution, c is the specific heat capacity of the solution, and ΔT is the temperature change.
