Potassium superoxide, KO2, is used in rebreathing masks to generate oxygen according to the reaction below. If the mask contains 10.655g KO2 and 1.802g water, how many grams
of oxygen can be produced?
4KO2(s) + 2H2O(ℓ) → 4KOH(s) + 3O2(g)

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:
