Nitrates

errors by taking my time and redoing the experiment a few times, but I did spill a bit of the liquid as a cut the pipets open. Also, my swabs may have been previously contaminated by the salt on our skin due to frequent use. MSDS INFO Barium Nitrate: Toxic/oxidizer: harmful if swallowed; avoid contact with eyes and skin; WARNING! VERY HAZARDOUS IF SWALLOWED. MAY CAUSE MODERATE TO SEVERE IRRITATION TO EYES AND/OR BURNS RESULTING IN CORNEAL INJURY. HARMFUL IF INHALED. CAN CAUSE IRRITATION

Our theoretical yield of Silver is 0.370 g, and our actual yield is 0.351 g. To begin with, I was amazed of the process of making silver from a little piece of metal and silver nitrate solution even though it took 3 days to complete this lab. On the first day, Michael mostly did all the measurements and testing, while Mai and I was responsible for the calculations, including taking pictures and recording down the data. Firstly, our group balanced out the chemical equation, which is very important

Nitrates is a venodilator that reduces myocardial oxygen demand by decreasing ventricular preload via vasodilation; it enhances myocardial oxygen delivery by dilating large coronary arteries and improving collateral flow to ischemic areas. The specific molecular mechanism of nitrates by acting through endothelial-independent pathway to relax all types of vascular smooth muscle cells .Nitrates are converted to nitric oxide which activates guanylate cyclase producing cyclic guanosine monophosphate

Majority of the experiment was conducted in a lighted area and this does not allow for a 100% reaction. Silver nitrate responds to light causing it to change its properities. It was important for students to quickly conduct the portions of the lab where silver nitrate was used. If not, then a less than 100% reaction would occur. It was also important for students to keep the silver nitrate in a dark area until needed. Finally, some source of errors caused by students, known as human errors, include

T he Stream Team tested the nitrate levels, air temperature, dissolved oxygen, pH, turbidity, and phosphate in the stream. The Nitrate test the average of all the tests taken where .25 mg/L.The air temperature of the day the test was taken was 11.7 degrees Celsius. The dissolved oxygen levels of the stream the day of testing were 5 mg/L.The average pH levels were 7.85. The turbidity of the stream the day we tested was 10 NTU.The phosphate level for the was not available because all tests performed

Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution then

Topic: Silver Nitrate Course Title: Analytical Chemistry 2 Course Code: PC223 Lab Group: D Prepared By: Ahd Mohamed Abdelmoniem Fahmi-175063 Due Date: 23-10-2017 Introduction about Silver Nitrate: Silver nitrate is an inorganic compound with chemical

If the amount of nitrates due to fertilizer runoff increases in an aquatic ecosystem, then the amount of algae in that ecosystem will increase at an accelerated rate. Four predictions coming from our experiment are if nitrate levels increase then algae growth will be accelerated. The second prediction is that if nitrates levels increase and algae increases then dissolved oxygen in the water will be at a lower level. The third prediction is that if nitrate levels increase in the water then the amount

noteworthy calamity happened to overall populace that for a long time after couldn 't be overlooked. It began on a brilliant and clear morning when the ship in the Texas City Harbor, The Grand Camp, loaded with ammonium nitrate compost, bound for war torn Europe, was ablaze. Ammonium nitrate is an exceptionally perilous and unstable material in the event that it is dangerously utilized, a similar material was utilized as a part of the Oklahoma bombarding. Since the flames in the port weren 't uncommon
