An ideal gas mixture containing 65.0 mol% carbon dioxide and 35.0 mol% nitrogen monoxide is to be prepared by allowing gaseous carbon dioxide to fill an evacuated 30.0 L cylinder to a pressure of 2.15 bar. The temperature is 415 K.(a) What mass of nitrogen monoxide gas NO must then be added to the cylinder to give the desired composition if the volume of the cylinder and temperature remain constant?(b) What is the total pressure of the final gas mixture?

Write a suitable mechanism for the cleavage of butyl isopropyl ether with HI at 100 degrees C to form exclusively isopropyl alcohol and 1-iodobutane. Explain why butyl alcohol and 2-iodo-isopropane are not formed in this reaction.
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP.
