A website that analyzes and reviews K-12 schools and colleges in the U.S., Niche.com, collected data to find which 25 high schools throughout the entire country produce the highest SAT and ACT scores. The information is based on self-reported scores from 75,834 test-takers at 909 schools from 2012-2014. In order to be considered in the findings, a school had to have at least 100 students submit their scores. Here are the 10 high schools with the highest national standardized test scores.
THE AMMONIA MANUFACTURING PROCESS Ammonia is produced in a process known as the Haber process, in which nitrogen and hydrogen react in the presence of an iron catalyst to form ammonia. The hydrogen is formed by reacting natural gas and steam at high temperatures and the nitrogen is supplied from the air 1. 2 + CO 2 Air is mixed in with the gas stream to give a hydrogen:nitrogen ratio of 3:1. Water, carbon monoxide and carbon dioxide (all of which poison the iron catalyst used in the ammonia synthesis) are removed.
But during this period, the chemistry of ammonia synthesis was being explored by the German chemists Fritz Haber and Walther Bosch who found that it was possible to produce ammonia from nitrogen and hydrogen by the process: N 2 + 3 H 2 2 NH 3.he Haber-Bosch process operates at high pressure so as to shift the equilibrium to the right, and high temperature to increase the rates of the reaction.
