Answer:
Volume of the helium will be 1.0L
Explanation:
To understand this question it is necessary to talk about 2 laws:
Charles's law that states: The volume of a given amount of gas held at constant pressure is directly proportional to absolute temperature.
Boyle's law that states: The volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
Now, in the problem, if you have 4.0L of helium:
If the temperature is halved and the volume varies directly with temperature (Charles's law), the volume of helium will be 2.0L
Then, the pressure es doubled and as volume varies inversely with pressure (Boyle's law), the volume of helium will be halved, being 1.0L.
Thus, <em>volume of the helium will be 1.0L</em>

In this item, it is assumed that we are to express the given compound in their ionic form. To be able to determine as to what ions this compound will dissociate into, we have the chemical reaction.
HNO3 --> H⁺ + NO₃⁻
Hence, the ions are H⁺, NO₃⁻.
