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.
Ammonia is a toxic, basic gas with the formula NH3. Ammonium nitrate is a solid, mildly acidic and potentially explosive salt with the formula NH4NO3. It is formed by the re â¦ action of ammonia with nitric acid.mmonium is a polyatomic ion with the formula NH4+. The ammonium ion is formed when ammonia reacts with an aci â¦ d and is itself mildly acidic. because it is positively charged is is not found on its own but accompanied by a negative ion such as in ammonium nitrate, NH4NO3.
