What else can I help you with?
Is the melting of table salt physical or chemical?
The melting point is a physical property of materials.
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 sanding a table top a chemical change?
Nope... sanding a table top is a physical change
If you mix table salt with water how can you proove that the dissolving was physical change?
Because when the salty water has evaporated, the salt and water have separated.
Why would the dissolution of table salt in water be considered gray area between chemical and physical change?
Because when the salt is dissolved, the chemical makeup of the crystal changes, making it a chemical change. However, you can evaporate the water, capture all the steam, cool the steam, and then you have the salt (original chemical makeup) and the water, making it a physical change.
Is dissloving a chemical or physical change?
Dissolving sugar or table salt in water is purely a Physical change
Is dissolving table salt is physical or 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.
Is dissolving table salt in a bowl of soup be chemical or physical change?
Dissolving table salt in a bowl of soup is a physical change because it doesn't alter the chemical composition of the salt or soup. The salt molecules simply spread out within the soup due to the intermolecular forces between the salt and water molecules.
How could you prove to someone that the dissolving of table salt was a physical change not a chemical change?
The chemical formula of sodium chloride is not changed by dissolution.
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.
When table salt is added to water the ionic compound dissolves. Does this represent a physical change or a chemical change?
Dissolving table salt in water represents a physical change, not a chemical change. The salt molecules remain intact and simply disperse in the water, without any chemical bonds being broken or formed.
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 the melting of table salt physical or chemical?
The melting point is a physical property of materials.
How could you prove that dissolving table salt in water is a physical change or not a chemical change?

Is possolving table salt in a glass of water a physical change of a chemical change?
It is a physical change because the chemical composition of the salt and water does not change.
