Is the transferring of Na to Cl to complete octets for both a physical or chemical change?
It is simply a chemical change.
What is a chemical equation for the dissociation of a soluble salt in water?
NaCl------------>Na+ + Cl-
Is salt forming a physical chance or chemical change?
It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.
How can you tell the difference between a chemical change and physical change in matter?
You can tell a chemical and a physical change apart because a physical change is any change in size, shape, form, or state where identity of the matter stays the same.Example of a physical: If you cut a watermelon into chunks, the watermelon has changed size and shape.If you put one of the chunks into your mouth and bite it you have changed the size and shape again.Chemical change occurs when one type of matter changes with different properties chemical change goes around you everyday.Signs of a chemical change are the formation of a gas.yes because i wrote it!
Is dissolving salt in water a chemical or physical change?
Physical (not chemical) changesNaCl(s) → Na+(aq) + Cl-(aq)Added:These are NOT chemical changes. In solid NaCl there are already Na+ and Cl- ions present in the (fully ionic)crystallic matrix. These ions are only separated by the water molecules. This is exactly what is called: 'dissolving'
How sodium chloride dissociates in water?
Dissolution is considered a physical process.

When sodium chloride is dissolved in watera chemical reaction occurs in which is the reactant?
It is not a chemical reaction, it is only a dissociation reaction:NaCl-------------------------Na+ + Cl-

What is the chemical formula for aqueous sodium chloride?
The chemical formula of sodium chloride is NaCl; in water solution, after dissociation, the ions Na+ and Cl- exist.

What is a chemecal change?
A chemical change (as opposed to a physical change) is when the actual chemical makeup of a substance changes. For example, Na+Cl->NaCl. A physical change on the other hand would be more along the lines of H2O(s)->H2O(l), (melting ice).
The dissociation equation for HCl?
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
Why dissolution of a salt in water a physical change?
The dissolution of salt in water is a physical change (not a chemical change) because even after the salt (NaCl) is all dissolved, it is still NaCl but in a ionized form, like Na^+ and Cl^-. So, there has been no chemical change at all, only a physical change in going from a solid to a solution.

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.
