Ammonium carbamate (NH2COONH4) is found in the blood and urine of mammals. At a temperature of 511 K, Kc = 0.056 for the following equilibrium: NH2COONH4(s) <=> 2 NH3(g) + CO2(g). If 10.2 g of ammonium carbamate is introduced into a 0.500 L container, what is the total pressure inside the container at equilibrium? Give your answer to 3 significant figures

When adding the solution of HNO3 from the buret in Step 14 to beaker 4, you know that you added 2.5 mL instead of 1.5 mL for a total volume of 11.0 mL. How would the calculated value of the equilibrium constant be affected for this sample?
Given that translational and rotational degrees of freedom typically behave classically, but vibrations behave quantum mechanically, the total (avg) energy of a diatomic is predicted to be U= (5/2)RT+ , where is obtained from Eq.124.
