How do you separate a mixture of ammonium chloride and chalk powder in the laboratory?

Oh, dude, separating ammonium chloride and chalk powder? Easy peasy. So, you just gotta add water to the mixture, 'cause ammonium chloride dissolves in water while chalk powder doesn't. Then you can filter out the chalk powder 'cause it won't dissolve, leaving you with the ammonium chloride solution. Like, science, man.
