question 41

Multiple Choice

Helium gas is being pumped into a rigid container at a constant temperature. As a result, the pressure of helium in the container is increasing. Select the one correct statement below.

• A)As the pressure increases, helium atoms move faster, on average.
• B)As the pressure increases, helium atoms move more slowly, on average.
• C)As the pressure increases, the volume of the container must decrease.
• D)As the pressure increases, helium atoms stay closer to the wall of the container, on average.
• E)As the pressure increases, there are more collisions of helium atoms with the container wall.

Definitions:

Resonance Hybrid

A composite representation of a molecule that cannot be depicted accurately by a single structural formula, illustrating electron delocalization.

Aromatic

Describes organic compounds that contain one or more planar rings of atoms with delocalized pi electrons, following Huckel's rule.

Nodal Planes

Imaginary planes in an atom or molecule where the probability of finding an electron is zero, often associated with molecular orbitals.

P Orbitals

Atomic orbitals shaped like dumbbells, consisting of regions where there's a high probability of finding an electron outside the nucleus, pivotal in chemical bonding and valence.
