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 chemical compound ammonium nitrate, the nitrate salt of ammonium, has the chemical formula N H 4 N O 3, simplified to N 2 H 4 O 3. It is a white crystalline solid and is highly soluble in water.mmonium nitrate is also used to modify the detonation rate of other explosives, such as ammonia-based dynamites, for example nitroglycerin and amatol. Numerous safety guidelines are available for storing and handling ammonium nitrate.
