Explanation:
At one end, new crusts are being produced, at other end the crust is being destroyed and this strikes a unique balance.
At the mid-ocean ridges, the lithospheric plates are diverging. This is implies that the earth is pulling apart here. When the earth is pulling apart, new materials from the asthenosphere comes to the surface thereby creating new lithospheric plate.
As new plates are formed, they push back against the old one. New plates are found very close to the margin and it begins to age away from the margin.
On the other end, old plates are taken away from this center to ocean trenches. At oceanic trenches subduction is occurring.
In a subduction, the lithospheric plate plunges deep into the asthenosphere where they are being melted back.
This is a covergent margin.
This process continues in a dynamic manner to cycle matter on earth.

Answer:
atomic mass ( N =14 , H = 1×3 that means 14+3=17
340gram×17gram / mole
=5780mole
atomic mass ( H= 1×2 ,O= 16 =16+2 =18
90gram×18gram /mole
=1620mole
I think 340g ammonia (NH3)
Answer; it’s either d or a. If it was be I would pick A. Not sure
Answer:
b) O2, because it has weaker intermolecular forces
Explanation:
The preassure is produced by the collisions of the gas molecules with the walls of its container.
When the intermolecular forces between the gas molecules increase, those molecules start to "slow down" by effect of the interactions. The collisions decrease in frequency and intensity producing a smaller preassure in the container.
Both O2 and Cl2 are non-polar gases and the only intermolecular forces they have are the London ones. Given that the O2 molecules are smaller than the Cl2, the last ones attract each other with more strengh.
Being all that said, the container with the oxygen is expected to have a higher preassure.
