This is a chemical reaction, a chemical change.
Sodium chloride is a chemical compound (NaCl), not a property.
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
Sodium chloride has the chemical formula NaCl and sodium sulfate has the chemical formula Na2SO4.
Sodium chloride is NaCl, calcium chloride is CaCl2. Consequently all the physical and chemical properties are different.
Sublimation is a physical change.
sulfur sodium chloride sand is a homogeneous mixture (solution)
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
The chemical name of sodium chloride is sodium chloride. The formula is NaCl.
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
Neither, Sodium Chloride (NaCl) is a salt (table salt) made by reacting the metal Sodium with the Gas Chlorine. The substance, Sodium Chloride, has both physical and chemical properties but is not a property itself.
The empirical formula of sodium chloride is NaCl.
