    I would rather go with A Cuzz it's obvious it's different from the physical propoerties as HCl is a liquid while H2 and Cl2 are gases

    The chemical properties will vary tooo cuz of the difference in masses ! @Photon336 what do u think about this ?

    Well for starters, HCL, H2, and Cl2 are entirely different compounds.

    they aren't the same compound, so both their chemical and physical properties will be different.

    Ok so I would cancel out D, and I looked more into the question and answers. So the answer is A im thinking. @Rushwr @Photon336

    @Jwhero Yeah, a compound has different chem/physical properties. for example, Chlorine Gas Cl2. HCl is acidic ---> H+ + Cl- while chlorine gas isn't acidic, HCl can exist as a liquid, while Cl2 and H2 are gases at room-temperatue.
