The melting point of sodium chloride is 801 0C.
This affirmation is not correct.
No, sodium chloride does not decompose when heated.
Sodium chloride is an ionic, polar compound.
No, it wont dissolve.
Sodium chloride become a liquid at 801 0C.
The concentration of sodium chloride increase.
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
the solid sodium chloride will dissolve in water.
Sodium chloride is very soluble in hot water.
because sodium chloride itself is madee up of positive sodium and negative chloride ions
Sodium chloride dissolve in water because it is an ionic compound.
Sodium chloride is a polar compound and cyclohexane is not a polar compound.
