Nitrogen gas may react with hydrogen gas to form hydrazine gas, N2H4, according to the reaction N2 + 2 H2 ---> N2H4. 10 L of N and 25 L H react to completion (the limiting reagent is converted entirely to hydrazine). What volume of the hydrazine gas will be produced if pressure and temperature are held constant? (Hint: Identify the limiting reagent and calculate the volume of the un-reacted excess reagent.)
