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.
It is chemical change
It is a chemical change because of sodium and hydrogen bonds forming
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
Making salt by mixing sodium and chlorine is it a physical or chemical which one
Assuming you're talking about salt forming as water evaporates: yes, that is a physical change. If you mean salt crystals forming from the combination of sodium and chlorine, then that's a chemical change.

this is a chemical change because you can't reyurn it back to salt
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
Physical
It is a physical change because the chemical composition of the salt and water does not change.
Mixing salt and pepper is a physical change
