one state would change   like louisiana to texas. thats a change

explanation:

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

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
