Maybelline Cousteau's backup oxygen tank reads 900 mm Hg while on her boat, where the temperature is 27 °C. When she dives down to investigate an unexplored methane lake on a recently discovered moon of Neptune, the temperature will drop down to "-183" °C. What will the pressure in her backup tank be at that temperature

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
