Asystem initially containing 2 mol c2h4 and 3 mol 02 undergoes the reactions: c2h4(g) + o2(g) → ((ch2)2)。(g) c2h4 (g) + 302 (g) → 2co2(g) + 2h2o(g) develop expressions for the mole fractions of the reacting species as functions of the reaction coordinates for the two reactions.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

What precautions should you take to prevent injuries when dealing with heavy loads?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
