Answer:
b. 0.453 mol
Explanation:
To convert atoms to moles, use Avogadro's number (6.022×10²³). Divide the amount of atoms that are given by Avogadro's number. You should get 0.453 mol.

Answer:
the attractive forces keep the particles together tightly enough so that the particles do not move past each other.
Explanation:
In the solid the particles vibrate in place.
Answer:
Correct option: D (both A and B)
Explanation:
Key things of bohr's model is that electrons occupy fixed orbital and required fixed amount of energy and electron must be in specific orbital and have precise amount of energy for that orbit
Niels bohr proposed a hydrogen atom model which explains the spectrum of hydrogen and he assumed that electron of hydrogen revolves around the nucleus in the circular orbit and bohr's model is valid only for single electron species.
statement of option A and B are correct
hence D is correct
