Ihave an evacuated 0.500 l flask at 298 k. i hook up my oxygen tank and flow oxygen into the flask until the pressure is 1.5 atm. then i hook up my nitrogen tank and flow nitrogen into the flask with the oxygen until the total pressure is 2.5 atm. what is the total pressure in the flask when the reaction has been completed?

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
