Explain A rigid 8.20 L flask contains a mixture of 2.50 moles of H2, 0.500moles of O2 and sufficient Ar thus that the partial pressure of Ar in the flask is 2.00 atm. The temperature is 127 degrees Celsius.
The mixture in the flask is ignited by a spark as well as the reactions represented below occur until one of the reactants is completely consumed.
2H_2(g) + O_2 (the arrow goes here) 2H_2O (g)
Give the mole fraction of ALL species present in the flask at the end of the reaction
