4. A student adds 50.0 mL of 0.25 M KCl solution to 25.0 mL 0.50 M AgNO3 solution. What is the mass of the precipitate that can be recovered if the percent yield of the reaction is 90%

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

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?
