A flask of ammonia is connected to a flask of an unknown acid HX by a 2.00 cm glass tube (where "X" represents a halogen). As the two gases diffuse down the tube, a white ring of NH 4 Xforms 137 cm from the ammonia flask. Identify element X (Name or symbol).
A student finds that 24.96 g of water at 24.9 C(density=0.9971 g/cm3) is required to completly fill an empty flask.
