What are the different physical properties between HCl and NaCl?
And explain the causes of their differences?
You will need to read in your text and look on the web for most of your information. First off, HCl is a gas and NaCl is a solid. HCl is a polar covalent bond while NaCl is an ionic bond. You can look up the boiling points, freezing points, delta H and that information. That should be enough to get you started.
