Hydrogen gas can be prepared by reacting metallic sodium with water: 2na(s) + 2h2o(l) → h2(g) + 2naoh(aq). if the price of sodium were 165/kg, what would be the cost of producing 1.00 mol of hydrogen. ignore the cost of the water.

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:
