Capillary pressure, as seen in petroleum engineering, is often modeled in a laboratory where it is recorded as the pressure required to displace some wetting phase by a non-wetting phase to establish equilibrium.
Asker's rating. 1  Ammonium nitrate is the chemical compound NH4 NO3. So there would be 3 different elements: nitrogen, hydrogen, and oxygen. 2  Ammonium nitrate is NH4NO3, making it three different elements: nitrogen, hydrogen, and oxygen. mmonkeyccup Â· 1 decade ago. 3  3 elements in ammonnium nitrate, NH4NO3. N from nitrogen, H from hydogen and O from oxygen. NH4 + + NO3---> NH4NO3. The compound consists of 2 polyatomic ions : first, NH4(1 positive charge) which consists of a)Nitrogen and b) Hydrogen, and the second one is NO3 (1 negative charge)consisting of Nitrogen and Oxygen.
The Hazards and Dangers of Ammonium Nitrate. What is Ammonium Nitrate? Ammonium nitrate is an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid. How is Ammonium Nitrate used? Ammonium nitrate is an important component of many fertilizer mixtures. It provides a sourceof nitrogen to plants, which increases growth and crop yields. Small quantities of ammonium nitrate are also sold as an additive for mining explosives and other nonagricultural uses. What are the potential hazards? Under normal handling conditions, ammonium nitrate is not harmful. However, inhalation of high concentrations of ammonium nitrate dust can cause respiratory tract irritation. Symptoms may include: coughing, sore throat, shortness of breath, or even suffocation.
