23. Consider the following gas phase reaction: 4NH3(g)+4NO(g)+O2(g)4N2(g)+6H2O(g) The initial partial pressure of each reactant gas is 60.0kPa, with the volume and temperature held constant. What is the mole fraction of H2O in the mixture after the reaction goes to completion? 24. A gaseous compound containing only C,H, and N is mixed with exactly the volume of oxygen required for combustion to CO2,H2O, and N2. Burning nine volumes of this mixture of compound and oxygen produces a gaseous mixture of four volumes CO2(g), six volumes H2O(g), and two volumes N2(g), all gas volumes being measured under the same conditions of temperature and total pressure. Write an equation for the combustion reaction, and find the number of volumes of oxygen required for the combustion and the molecular formula of the compound
