Explanation:
Liquids cannot change volume but gases can because they have a fixed shape like solids.
Liquids have strong intermolecular forces binding their molecules together resulting is fixed ordering.
- Gases are randomized with their molecules haphazardly arranged.
- This allows them to expand spontaneously on their own.
- Molecules of liquids are more tightly packed compared to gases.
- In a liquid, the molecules have a less random pattern of motion and can only slide past one another.
- In a gas, the molecules are in continuous random, straight line motion.

I think the number of protons in the nucleus the number of valence electrons atomic mass...
In an ionic bond, one atom essentially donates an electron to stabilize the other atom. The atoms in an ionic bond have different electronegativity values from each other.
While in a covalent bond, the atoms are bound by shared electrons and the electronegativity values are the same.
Answer:
You start with 9.4 x 1025 molecules of H2.
You know that an Avogadro's number of molecules of H2 has a mass of 2.0 g.
To solve, 9.4 x 1025 molecules H2 x (2.0 g H2 / 6.023 x 1023 molecules H2) = 312. g H2
