Ammonium nitrate

Mulvaney, 1982). Nitrate nitrogen (NO3−-N) and exchangeable ammonium nitrogen (NH4 +-N) in soil was determined using FeSO4/Zn reduction method described by Carter (Carter, 1993). Total P in soil was determined using Sodium carbonate fusion described by Carter (Carter, 1993). Available phosphorus (P) in soil was determined by extracting samples with 0.5 M NaHCO3, and…

Sunflower plants grow well in average to rich soils. They need to grow their roots deep and wide, to enable them to withstand strong winds. If you have a choice, sandy soils are not recommended, as they are easily uprooted in loose soil. Rich soil is important, when growing giant varieties. Contrary to its name, we found they will tolerate some shade as we put them against an east wall of our house every year. However, they will grow their best in full sun. Deep roots help sunflowers to…

There are many countries in the world that have not been able to become fully developed economically. For those countries that are developed, they are usually around the same region. Many of the more developed countries are located in Europe, North America and some exceptions in Asia. However, that is not always the case, the Caribbean, although a small part of the world, has surprisingly a few countries that are either developed, or in the process of developing. The country that this research…

Laughing gas has been used as an anesthesia for dentistry since 1844. Up to today, it has been used for many other medical procedures and surgeries, but it is widely known and used for oral surgeries. The procedure of laughing gas in surgery is very simple, Dinitrogen monoxide (N2O) is a gas in which you inhale. When you inhale the colourless gas, it reaches the brain in around 20 seconds and it starts to relax your body and develop pain-killing properties to keep you composed and calm. You…

Introduction For the most part, the periodic table groups atoms together which are similar in structure and property. Groups or columns share similar electronic configurations, on which a variety of properties are based1. In the lab, the tested elements include those from Group 1, Group 2, Period 3, Period 4, Period 5, Period 6, and a series of metals (Calcium, Copper, Iron, Magnesium, Tin, Zinc). Group 1 elements have one valence electron and are extremely reactive. Most of the time, compounds…

The problems of low NUE in organic agriculture are more complex than the simple adjustment of fertilization methods. In the absence of synthetic N application, N uptake depends on the size of the root absorbing area and root uptake efficiency, existing inorganic N and potential N mineralization reserves in the soil (Spiertz & De Vos, 1983). Since the principle is based on utilization of already existing ecological systems and recycling process, the main concept in the improvement of NUE in…

Fishing. People enjoy it a lot as a hobby or career whether it’s for a bonding experience between family or friends or a way to survive. But could it be too much? We have of plenty of fish, right? Wrong. Small fishing in ponds, lakes, and sea sides by one or two people won’t make much of a difference, but with the main fishing companies hauling thousands to millions of marine life out of the oceans daily, it will be. This is overfishing; depleting stocks of fish in a body of water by too much…

Waco, Texas standoff caused McVeigh to “snap”. He believed the government was being cruel to the citizens of America, and believed they should be punished. His form of punishment was loading a rented Ryder truck with upwards of 5000 pounds of ammonium nitrate. The bomb detonated near the Alfred P. Murrah Federal building, killing 168 people, multiple of which were children, and injuring over 600 more. McVeigh later admitted he did not know that there were children present in the building, and…

white precipitate when the compound was added to 6 M HNO_3 and AgNO_3 for the chloride test and 6 M HCl and BaCl_2 for the sulfate test. There were no indications of the other anions in our compound. A brown ring did not form for the presence of nitrate, there was no indication of fizzing for the presence of carbonate, and no fruity smell for the presence of acetate. With this we can further conclude that our compound is either NaCl or Na_2 SO_4. We know this from the fact that if chloride is…

ethanol for 30 min followed by 30% ethanol for 30 min. The gels were then sensitized for 1 min in 2% solution of sodium sulfite (Na2SO3) followed by rinsing three times with Mili-Q for 20 sec and were stained for 20 min in staining solution [1M Silver nitrate (AgNO3) and formaldehyde (HCHO)]. After staining, gels were rinsed thrice for 20 sec in distilled water and developed for 5–10 min in a developer [sodium carbonate (Na2CO3) and formaldehyde (HCHO)] and observed for the appearance of intense…
