Source sentences:
text: Mass production of ammonia mostly uses the Haber–Bosch process, a gas phase reaction between hydrogen (H 2 ) and nitrogen (N 2 ) at a moderately-elevated temperature (450 °C) and high pressure (100 standard atmospheres (10 MPa)):
text: Nitrate is relatively non-toxic to fish and may safely accumulate in the tank until it is flushed out by replacement water or converted to gaseous nitrogen (N 2 ) by anaerobic heterotrophs and lost to the atmosphere in a process known as denitrification.
text: But that year, German scientist Fritz Haber found a reaction that, with the aid of iron catalysts, could split the tough chemical bond that holds together molecules of nitrogen, N 2 , and combine the atoms with hydrogen to make ammonia.
text: Water reacts at the anode to make hydrogen ions (H + ), which migrate to the cathode where they react with nitrogen (N 2 ) to form ammonia.
