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.
Best Answer: In ammonium chloride, you don't have any ammonia - all the ammonia is protonated, the species you do have are ammonium (NH4+) and chloride. If you want to include water, all you can do is indicate the dissolution - because that's what happens first: NH4Cl (s) + n H2O ---> NH4+ (aq) + Cl- (aq)
