Answer:
P (H₂) = 741 torr
Explanation:
Let's begin by listing out the given parameters:
Temperature (water) = 298 K, volume = 45.6 mL,
atmospheric pressure, P (total) = 765 torr, vapor pressure of water, P (H₂O) = 24 torr
To get the pressure of inside the tube, P (H₂), we apply Dalton's Law of Partial Pressure and we have:
P (total) = P (H₂) + P (H₂O)
P (total) = 765 torr, P (H₂O) = 24 torr
P (H₂) = P (total) - P (H₂O) = 765 - 24
P (H₂) = 741 torr
It therefore becomes clear that the pressure of H₂(g) is 741 torr

(3) It involves interactions between biotic and abiotic
factors.
Explanation:
An ecosystem involves the interaction between biotic and abiotic factors.
The biotic factors are the living components of the ecosystem. The abiotic factors are the non-living components.
An ecosystem is made up the interaction between living organisms and their environments.
- Ecosystem are combination of the community of lives and the environment.
- The environment contains the non-living abiotic components.
- The organisms are the living components.
- All of this merges together to form of the ecosystem.

A = number of mass = 31 => number of protons + number of neutrons = 31
Phosphours, Z = atomic number = 15 = number of protons
Symbol of the element phosphorus = P
=> The symbol of the isotope is the symbol of the element, P, with the number of mass, 31, to the left, as a superscript, and the atomic number, 15, to the left, as a suscript.
