On heating it sublimes and the vapor easily crystallizes to a solid again. Salt has a much higher melting point and sand extreemly high.
NaCl, table salt, and ammonium chloride will both dissolve in water. Sand is only sparingly soluble in water. If you want to further separate ammonium chloride from sodium chloride, you will need to dry the resulting solution. The sodium chloride will precipitate out first. The ammonium chloride will remain in the supernatant and can be poured off leaving the sodium chloride crystals behind.
The physical property of oxygen that enables it to be separated from the other components of air is its higher boiling point compared to nitrogen. This difference in boiling points allows for distillation or fractional distillation processes to separate oxygen from the air mixture.
Your mom! hahaha jk, its the communitive property
Malleability
freezing point.........................
density
Conductor
amphipathic molecules
The property of a salt that enables it to absorb water from the atmosphere is known as hygroscopicity.
Potassium chloride dissociates into ions (K+ and Cl-) in aqueous solution, allowing for the movement of charged particles. This movement of ions enables the flow of electricity, making potassium chloride a conductor in aqueous solution.
Primarily it is its low boiling point and hence volatility that enables smell/aroma. There are other factors too.
Surface tension is the property that enables a pin to float on water. It is the result of the cohesive forces between water molecules at the surface, creating a sort of "skin" that can support the weight of small objects like a pin.
