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.
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.
Is a skateboard a physical change?
No its a chemical change
Is sanding a table top a chemical change?
Nope... sanding a table top is 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 dissloving a chemical or physical change?
Dissolving sugar or table salt in water is purely a Physical change
When table salt forms from its elements is it chemical or physical change?
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
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.
Is mixing sodium chloride and water a chemical or physical change?
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
Is adding NaOH to HCL chemical or physical change?
When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
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.
How could you prove that table salt in water is a phyical change not a chemical change?
that is because salt is a physical matter
