Ammonia is manufactured in an exothermic reaction between nitrogen and hydrogen in the presence of an iron catalyst: The nitrogen and hydrogen mixture is passed into a reaction chamber at a pressure of 200 atmospheres and a temperature of 4500C. The reaction is reversible. (a) Why is a catalyst needed? The mixture of gases leaving the reaction chamber still contains some unreacted nitrogen and hydrogen- and Explain how the ammonia can be separated from this unreacted nitrogen and hydrogen. (c)...

3.0 PROCEDURE: For each reaction, you should write a total molecular reaction, a total ionic reaction and then remove any spectator ions to produce a final net ionic reaction. In order to simplify your task each reaction has its driving force listed. In more advanced General Chemistry courses, you will be expected to find the driving force yourself (based on the rules given above), but for our purposes it is best for you to simply "experience the steps of producing...

A) Draw the beaker at the end of the reaction - what would e in
the beaker and/or around it. What would the products look like on a
molecular/atom/ion level?
B) At STP, how many L of your gas was produced? (ignore water
vapor)
C) Why would water vapor pressure be involved in this
reaction?
D) Assuming the aqueous volume given in the problem remains the
same, what is the molarity of the two ions in the reaction at the...

2. What will you observe when you have a positive test for: (a) bicarbonate anion(HCO3-)? • Bubbles Dobre lieT like gas o colorless (b) phosphate anion(PO43-)? 1. A student studied some reactions involving Pb2+ ion, copper(II) ion (Cu2+), and nickel(II)ion (Ni2+). The student first observed the behavior of individual solutions of Pb(NO3)2, copper(II) nitrate, Cu(NO3)2, nickel(II) nitrate, Ni(NO3)2, interacting individually with 1M HCl solution and then individually with 1M sodium hydroxide solution (NaOH). The student also added an aqueous ammonia...
