How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
Is the melting of table salt physical or chemical?
The melting point is a physical property of materials.
Is sanding a table top a chemical change?

Chemical change because physical change is just altering the physical appearance of something, like tearing a paper in half, that is a physical change.
How could you prove to someone that the dissolving of table salt was a physical change not a chemical change?

When table salt dissolves in water is it a physical or chemical property?
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
Is dissolving table sat in a jar of water and the salt being left behind a physical change?
Dissolving in water is a physical change. Evaporation of water also.
Is salt dissolving a chemical reaction?
Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.
Is dissolving a solid a physical or chemical change?
it depends on if the solid is also water. if they are both water then its a physical reaction because it just changes the state of matter. if the solid isn't water then its chemical because the two substances then transform into one new substance.
Is the melting of table salt physical or chemical?
The melting point is a physical property of materials.
Is sanding a table top a chemical change?
Nope... sanding a table top is a physical change
Is possolving table salt in a glass of water a physical change of a chemical change?
