A cylinder contains helium gas with a volume of 2.60 L at 20 C and 768 mm Hg. If the balloon ascends to an altitude where the helium pressure is 614 mm Hg, what is the volume of gas? (Assume the temperature has not changed)

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
