Because it changes directly from solid to gas when heated. It sublimes.

Why hydrogen chloride is a liquid while hydrogen chloride is a gas?
At the standard temperature and pressure, hydrogen chloride exists as a gas. It does not exist in liquid state, but in aqueous medium along with water as a solvent.
Why does ammonium chloride disappear when kept open?
Ammonium chloride appears to sublime but in this process solid NH4Cl actually (chemical) decomposition into ammonia and hydrogen chloride gas is involved. NH4Clsolid → NH3,gas + HCl,gasAmmonium chloride only likes to be a sublimable solid (one which changes from the solid state to gaseous state without passing through the intermediate liquid state)it sublimes at room temperature ie 25 degree centigrade thus it evaporates,and disappears when kept open.A real example of (pure physical) sublimation is Iodine, I2,sol → I2,gas
How could iodine be separated from salt?
Iodine can be separated from salt by the process of sublimation.Sublimation is the process of conversion of a material from solid state to gaseous state without undergoing liquid state.Some sublimate objects are ammonium chloride,iodine,moth balls,camphor,etc.
How many atoms are there in aluminum chloride?
Four or eight, depending on the state. It exists as AlCl3 or Al2Cl6.
What state of matter is ammonium?
ammonium is in the state of matter
What is the oxidation state of ammonium chloride?
Ammonium chloride doesn't have one oxidation state, there are multiple. But ammonium itslef has an oxidation state of +1 and Chlorine is -1.
What was given off when ammonium chloride was heated?
since ammonium chloride is a subline solid, it gets converted into gaseous state directly without changing into liquid state
Is ammonium hydroxide the same as ammonium chloride?
No they are not same. Ammonium hydroxide is a weak base, an aqueous compound in normal state. Ammonium chloride is a an acidic salt and is a white powder in normal state.
What is the oxidation state of chloride?
Ammonium chloride doesn't have one oxidation state, there are multiple. But ammonium itslef has an oxidation state of +1 and Chlorine is -1.
Why hydrogen chloride is a liquid while hydrogen chloride is a gas?

What is the state of ammonium chloride?
Solid, i think..
Is ammonium chloride soluble in water?
Solubility of NH4Cl varies with temperature. At 0 degrees Celsius, the solubility is 29.7g/100mL in water.
How do you Separate ammonium chloride from sand?
heat the mixture until you no longer see white fumes, then stir the mixture to make sure all of the ammonium chloride is sublimed (solid moved to a gaseous state without passing through the liquid phase. All that should be left is the sand.
Could NH4 be a gas?
NH4 is an ion. It does not exist under normal conditions. It may exist in combined state as Ammonium Chloride NH4Cl (which is a sublimates and exists only in solid and gaseous state), Ammonium Nitrate NH4NO3, Ammonium Sulphate (NH4)2SO4 which may exist in gaseous state at high temperatures. In case you are talking about Ammonia which is NH3, then yes,it is a gas under normal conditions but becomes a liquid on bubbling through water. (Ammonia solution of varying concentrations), much like Hydrogen Chloride, which on bubbling through water, forms, Hydrochloric acid in varying concentrations.
What happens when sodium chloride melts?
It goes from the solid state to the liquid state.
What happens to ammonium chloride when heated?
when ammonium chloride is heated its particles get converted into gaseous state i.e vapours of ammonium chloride due to sublimation.
What is the difference in meaning of the two terms sodium chloride in its liquid state and a solution of sodium chloride?
Liquid sodium chloride would be salt in its molten state... in solution, salt is dissolved in another liquid, often water..
