No. It is only a chemical change if the properties of the atom (or in this case ionic compound) are completely changed. This means anytime a chemical bond in that molecule is broken or formed, it's a chemical change.
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.
Yes, melting sodium chloride is a physical change because it involves a change in state from a solid to a liquid without altering the chemical composition of the substance.
NaCl (sodium chloride)
This is a chemical reaction, a chemical change.
The melting point of sodium chloride is 801 0C.
The melting point of sodium chloride is 801 0C.
The melting point of sodium chloride is 801 0C.
Some water that has bonded with the salt will be removes but otherwise salt is remarkably stable. Eventually (when it gets hot enough) you will ionize it into Cl and Na ions.
the chemical name is sodium chloride, but if you need to be specific then i don't know what the name is, but i do know that one of the names is sodium chloride. sorry if i couldn't be of any assistance.
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.
When sodium chloride and silver nitrate react, they form silver chloride precipitation and sodium nitrate in solution. This is a chemical change as new substances are formed with different properties from the original reactants.
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.
