Which has the higher enthalpy under these conditions, 2 o3(g) or 3 o2(g)?

it should be all of them because it asks if you included all of those in your answer

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

answerca air mass;
