How are hydrospheres and atmospheres similar? List an example

Please help me.

The “sphere” in the lithosphere, atmosphere, and hydrosphere means envelop. The atmosphere, therefore, consists of gases that envelop the Earth. The hydrosphere defines the water that covers 71% of the Earth's surface. As you go higher in the atmosphere, the mixture of the gases changes.

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

2.4

24

catya your not at all which answer i've seen you do this on another question!
