Answer:
The pressure inside the flask is 0,09 atm
Explanation:
We calculate the number of moles of O2, we convert the Temperature into unit KELVIN and use the formula of the ideal gases to calculate the pressure:
Weight 1 mol of 02= 15,999g x2= 32g
32g---1mol 02
0,60g---x=(0,60gx1mol O2)/32g= 0,019mol O2
T(K)=273+22=295K
PV=nRT
Px5.0l= 0,019mol x 0,082 lxatm/Kxmolx295 K
P=(0,019mol x 0,082 lxatm/Kxmolx295 K)/5.0l
P=0,09atm
C) Stars get born, get older, then eventually die.
The main factor is the size of the moon. which is small compared to the earth, meaning that the moon has less gravity, and more gas is allowed to escape the surface, Which basically means theres no atmosphere.

Answer:
[D] Same Phylum
Explanation:
To know the least closely related We need to the know this:
- Domain
- Kingdom
- Phylum
- Class Order
- Family
- genus
- Species
Domain → Broadest ⇒ Least related.
Thus, In the answer choices we know that Phylum is the least Closely related.
