Which of the following best explains what happens when you add ice to a glass of water? The water becomes warmer because it gains heat energy from the air.
Heat energy moves from the ice cubes to the water.
Heat energy moves from the water to the ice cubes.
The ice cubes make the water colder by releasing coolness into the water.

I think it would be the last one

Explanation:

I apologize if that is wrong

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
