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.
Ammonium nitrate (AN) is an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid. It was the first solid nitrogen (N) fertilizer produced on a large scale.mmonium nitrate is more popular than other nitrogen fertilizers for pasture and hay fertilization since it is less susceptible to volatilization or air losses when left on the soil. It is also valued by vegetable growers for its ability to provide an immediately available nitrate source of plant food.
