The pure N2(g) required for the ammonia synthesis reaction will be taken from air. This is done with an air liquifaction plant. Suggest a way this might work based on knowledge of phase equilibrium. To do this first consider air to be made up of only N2 (78 mole %), O2 (21%), and Ar (1%) and estimate the mole fractions of each in both liquid and gas phases if one mole of air at 300 K as well as 4 atm total pressure is cooled to 65 K in the same volume.
Using your mean experimental value of R =20 ,and of n= 1.00, calcuate the molar volume of your H2 at STP (standar T=273 K,P= 760mm Hg),using the ideal gas law
A 1L flask is filled with 1.00 g of argon at 25 C . A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm. What is partial pressure of Argon and ethane in the flask?
In an ion, the sum of the oxidation states is equal to the overall ionic charge. Note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered.
