Answer:
Diatomic molecules consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Many compounds are diatomic, such as HCl, NaCl, and KBr. Diatomic compounds consist of two different elements. There are seven pure elements that form diatomic molecules.

sun‘s life cycle
1. nebula
2. protostar
3. sequence star (sun is this currently)
4. red giant
5. white dwarf
6. black dwarf
bigger stars
1. nebula
2. protostar
3. sequence star
4. red super giant
5. supernova
6a. black hole
or
6b. neutron star
Sun was a protostar
is currently a main sequence star
will remain so for another 4-5 billion years.
It will then expand and cool to become a red giant
after which it will shrink and heat up again to become a white dwarf
The white dwarf star will run out of nuclear fuel and
slowly cool down over many billions of years
black dwarf

Answer:
2.7 × 10⁻⁴ bar
Explanation:
Let's consider the following reaction at equilibrium.
SbCl₅(g) ⇄ SbCl₃(g) + Cl₂(g)
The pressure equilibrium constant (Kp) is 3.5 × 10⁻⁴. We can use these data and the partial pressures at equilibrium of SbCl₅ and SbCl₃, to find the partial pressure at equilibrium of Cl₂.
Kp = pSbCl₃ × pCl₂ / pSbCl₅
pCl₂ = Kp × pSbCl₅ / pSbCl₃
pCl₂ = 3.5 × 10⁻⁴ × 0.17 / 0.22
pCl₂ = 2.7 × 10⁻⁴ bar
Evaporation because water absorbs the heat so the particles have more energy and can break away from bonds holding them together (turn to gas)
