In a mixture of hydrogen and helium gases, the mole fraction of helium is 0.750. If the partial pressure of hydrogen in the mixture is 75 torr, what is the total pressure of the mixture?a. 100 torr b. 300 torr c. 19 torr d. 750 tor e. 760 torr

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:

How do you determine the percent yield of a chemical reaction

Is water wet? my friends are debating.
