Nitrate

grow as it is used in the synthesis of precursor molecules such as DNA, and forms back-born of protein molecules necessary for growth. Maize requires nitrogenous fertilizers and the nitrogen is taken up by the crop in the form of ammonium NH4+ and nitrate form…

The independent variable is the water samples taken. A dependant variable is the variable being measured during the experiment. The dependant variables are the salinity, turbidity, dissolved oxygen, pH, nitrates, phosphates, and the temperature of the water samples obtained from each pond. Factors that are deliberately held constant is the the amount of millilitres gathered from each location, and the method of the testing. Method pH A small sample…

Gunpowder is one of china’s four greatest inventions. Gunpowder is an ancient chemical explosive that was accidently created by Chinese Taoists who were attempting to create a portion of immortality by combining salt peter, sulfur, and charcoal. There are multiple types of gun powder: Black powder (organic), black powder (modern / synthetic), cordite, smokeless ball powder (aka spherical powder), smokeless flake powder (found in shot shells), and smokeless stick powder (aka extruded powder).…

why that is the only part that produces a taste. As the amide is hydrolyzed by either an acid or base catalyst, methanol is produced as a byproduct and it is this alcohol byproduct that was tested for using potassium permanganate and ceric ammonium nitrate. The acid catalyzed hydrolysis mechanism for this reaction is pictured…

Introduction Unknown substances can be found everywhere. Whether it is the mysterious crust on the desk, or the sticky material found at the bottom of an unwashed bowl, there is a curiosity as to what that substance could be. In science, the unknown substance is called the analyte (1). The unknown substance, taken from the Gulf of Mexico, is tested to determine the true identity of the substance. In order to find the analyte, there are two different scientific methods that can be applied. The…

supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate. After comparing the results of these experiments we determined that our compound contained a halide. By using the flame test with a Bunsen Burner we also determined that our compound had a red colored flame leading us to our…

I started with the gram negative bacillus by performing the nitrate reduction test and the urease test. I chose these two tests because I knew that a positive urease test would indicate that the gram negative bacillus was P. rettgeri, but this test came back negative after I performed two just to make sure that the results were accurate. Also, the nitrate reduction test could have indicated that the gram negative bacillus was P. fluorescens, but the test result…

But the goal of the chapter was that sometimes just going out and observing your land is the most powerful and effective thing you can do. Not spraying for pests, not spraying nitrates for “insurance” reasons, simply turning off the tractor and watching. You will then notice things that are unnatural as well as things that you may think are a nuisance, but in reality, they don’t affect your farm at all. Chapter 7, “Stewards of…

as a siderophore to chelate iron when the concentration of iron is low. Whenever the concentration is low, it would show fluorescent pigments under UV light. Although this unknown was tested negative for the presence of nitrate reductase, there are certain strains that uses nitrate as the terminal electron…

Taking tadalafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Some medicines can cause unwanted or dangerous effects when used with Cialis. Tell your doctor about all your current medicines, especially riociguat (Adempas). Contact your doctor…
