NH3 1 of 19 What is the process of making Ammonia from the raw materials Nitrogen and Hydrogen? The Haber Process 2 of 19 In the process of making Ammonia what temperature is needed? 450 3 of 19 In the process of making Ammonia what pressure is needed? 200 atm 4 of 19 What is the Catalyst in the process of making Ammonia? Iron 5 of 19 What happens to the unreacted Ammonia from the Haber Process? It passes into a cooling tank (with the unreacted Nitrogen and Hydrogen) where the Ammonia is liquefied and removed into pressurised storage vessels. 6 of 19 What happens to the unreacted Nitrogen and Hydrogen from the Haber Process? They are pumped back into the reactor 7 of 19 What do both the Haber Process and the Contact Process contain? Reversible reactions 8 of 19 What is the first stage of the Contact Process? Burning sulfur in air to make sulfur dioxide 9 of 19 What is the second stage of the Contact Process? Sulfur dioxide reacts with more oxygen to make sulfur trioxide 10 of 19 What temperature is needed for the second stage of the Contact Process? 450 11 of 19 What is the catalyst for the second stage of the Contact Process? Vanadium Oxide 12 of 19 What pressure is needed for the second stage of the Contact Process? 2 atm 13 of 19 What is the third stage of the Contact Process Sulfur trioxide reacts with water to form sulfuric acid 14 of 19 What is the chemical formula for sulfuric acid? H2SO4 15 of 19 What is the majority of sulfuric acid used for? Fertiliser by reacting with ammonia/ammonium hydroxide to make ammonium sulfate 16 of 19 Name the formula for common salt? NaCl 17 of 19 What is solution mining? Hot water pumped into salt deposits underground, reacts with the salt to form a solution and is pumped back up 18 of 19 How are Hydrogen, Chlorine and Sodium Hydroxide manufactured? Electrolysis of brine 19 of 19
