Nitrate

Kumale Fufa Ramisha Islam 18 November 2014 Period 1, Period 2 The Effect of Different Levels of Nitrate and Phosphate in Fertilizer Runoff Before and After Rain Water is a major resource and is essential for life. It is naturally recycled through a process called hydrological cycle. The demand of water over the world has been increasing as population and industrialization does, while available drinking water has been deteriorating due to pollution.Fertilizer runoff is a serious…

Laboratory Analysis Justyna Sudyka 1. a. Clostridium sporogenes grew throughout all of the thioglycollate broth, but there was more growth towards the bottom. The aerobic TSA + glucose plate did not have any growth, but the anaerobic plate did have growth. Escherichia coli grew throughout all of the thioglycollate broth as well, but the organism was clustered slightly more towards the top. There was growth in both aerobic and anaerobic TSA + glucose plates. Micrococcus luteus only grew at the…

centering disk and thruster disk. The third section is to conduct series of firing test. Lastly, all parts will be assembled preinstalled with rocket body and recovery sytem. Potassium Nitrate is use as a basis of propellant grain. Potassium Perchlorate has higher specific impulse than Potassium Nitrate. However, Potassium Nitrate is more simple and less dangerous than Potassium Perchlorate. Chemical Propellant Advantages Disadvantages Solid Propellant - fuel not dangerous which easier to…

Station 3 analyses the quality of water within Baldwin Swamp through investigating the pH Level; the turbidity; the waters dissolved oxygen, nitrites, nitrates, ammonia and temperature. The obtained results convey the pH was neutral in 2009 but is currently 5.95, the equivalent of a normal river stream or that of milk. This Ph level is great because nutrients are most available to plants in the optimum 5.5 to 7.0 range, making the difference in the pH not effective to plants. These Ph levels…

After the alkyl halide was formed, silver nitrate test and the sodium iodide test are done to classify the compound. These halide tests are done to characterize and assess the molecule by determining which functional groups the product contains. The silver nitrate test reacts in a Sn1 reaction while the sodium iodide test reacts in a Sn2 reaction. Thus, a reaction with the silver nitrate to a product with a tertiary carbon will react faster than for a secondary carbon…

flasks (1L) containing 200mL of Potato Dextrose Broth (10g/L Great Value mashed potatoes with 5g/L D-glucose). One of the five flasks received approximately 1.0-1.3g of the following metal compounds: cobalt (II) chloride hexahydrate, cobalt (II) nitrate hexahydrate, cobalt (II) thiocyanate, erbium chloride hexahydrate, or palladium (II) acetate. The sixth flask was reserved as a control and only contained PDB. Salcha-1 was incubated on an Innova 5000 shaker at 135rpm for three weeks at room…

The nitrogen in the ecosystem is from natural events. Nitrates are mostly ammonium and nitrate. This compound is used in the ecosystem for the growth, repair, and reproduction of plants. Nitrogen appears in a lot of natural processes. Some plants take atmospheric nitrogen and convert it to nitrogen that they can actually use…

sodium hydroxide (NaOH), a strong base, also had no visible reaction. However, the resulting solution was a lot more basic. Reacting the unknown compound with sodium nitrate (NaNO3), a salt, did not have a visible reaction nor did the pH of the resulting solution change. The last reaction involved the unknown compound and silver nitrate (Ag(NO3)2), another salt. A milky, white precipitate was produced (AgCl2) and there was no change in pH. After performing these reactions, it was apparent that…

the flask was weighed again, weighing 91.072 grams, indicating that the weight of the dissolved solute was .76 grams. The reaction was as follows: Ca + 2H2O-> Ca(OH)2 + H2 . The Calcium in the unknown reacted with water, rather than dissolving. Nitrate is always soluble in water, but calcium will form a precipitate of Ca(OH)2 since it reacts with water. The precipitate will have a solubility 0.79g/15mL, or…
