chemical change for example could be NaCl + HgNO3 -> NaNO3 + HgCl
physical change is as simple as breaking salt crystals into smaller pieces

You could just google it.
Chemical: Melting it
Physical: Breaking it

Staining it with dye or cooking it

Dissolving would be a physical change.
A chemical change would be breaking it down by burning it.

chemical changes will make it change to another substance. if you melt it, it will come back salt once it cools. but salt has an extremly high melting points so i doubt ull melt it. also dissolving would be a physical change cuz when the water dries, the same amount of salt is there. breaking it would also be a physical change because it will still be salt. the only chemical change is if you somehow split it into the different elements

If you run an electrical current through salt, you can separate the two base elements.

Chemical changes are hard to reverse. Not so with physical changes.
