A large closed tank ofcompressed air is connected by a hydraulic line of diameter d=5cm.and filedwith oil(SG=0.9), toa frictionlesspiston oftotal mass M=100kg. Determinethe air gage pressure required to lift the piston toa height of 2m above the air-fluid interface in the large tank, as shown.
The standard free energy change for the reaction of nitrogen gas with hydrogen gas to produce ammonia is -32.9 kJ. Calculate the equilibrium constant for this reaction at 25°C.
If the reaction is allowed to proceed until all substances have reached their equilibrium concentrations, determine delta G for the reaction.
If equal masses of both metals were transferred to equal volumes of water in seperated graduated cylinders, which graduated cylinder would have the greatest volume change. why.
Find the heat transferred (in kJ) when 5.55 L of ethylene glycol (d = 1.11 g/mL) in a car radiator cools from 40.0°C to 25.3°C.
