Nitrates

“The Law of Conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant.” (University Of Wisconsin) The data the was found from our lab shows that the data is not consistent to the Law of Conservation of Mass because our results showed an increase in mass. To start the lab, .7 grams of copper was measured out and at the end, the total amount of copper was…

After the incubation period, the agar containing the antibiotic testing was taken out and if the microbe reacted with the antibiotic, a circle or clearing would appear around the disk containing the antibiotic. The diameter of this circle was then measured and compared with a table found on page 95 of the Microbiology Lab Manual to understand the antibiotics resistance, intermediate and sensitive levels, as they differ for each antibiotic. The numbers on the table in the Microbiology Lab…

aluminium oxide. (6) was identified as zinc carbonate due to evolution of CO2 on addition of sulphuric acid. Among the soluble solids, two (1 and 12) formed precipitates in sulphuric acid. One was expected to be Barium chloride and to react with silver nitrate. Hence, (14) and (13) were reacted with 1 and 12. This led to the identification of 1 as barium chloride and 13 as silver…

Concentrated Animal Feeding Operations or also known as CAFO’s are another cause for the contamination of water. CAFO’s are giant livestock farms where thousands of chicken and cows are housed into small confinements and live in horrible conditions. When so many animals are stored in a limited space manure will become a problem for the farm, according to the Union of Concerned Scientists, “CAFOs produce some 300 million tons of untreated manure each year (about twice as much as is generated by…

1947, in the Port of Texas City, it’s was the deadliest industrial accident in U.S. history, and one of the largest non-nuclear explosions. Fire started on board the French-registered vessel SS Grandcamp her goods of roughly 2,300 tons of ammonium nitrate ignated, with the initial blast and with chain-reaction of further fires and explosions in other ships and nearby oil-storage facilities killing at least 581 people, including all but one member of the Texas City fire department. The disaster…

Following WHMIS, it is vital that safety be a priority when conducting labs. Especially when handling chemicals, the ideal setup of labs should avoid any obstructions and potential hazards that may occur. This is due to the possible dangers: flammable and combustible chemicals (alcohol, sodium), oxidation (hair dye), bio hazardous products (which causes AIDS, rabies), toxic items (lead, benzene), poison (carbon monoxide), corrosive compounds (bleach), dangerously reactive chemicals (fluorine)…

who use a variety of fertilizers…” To start off, Emerald Estates water sample did not produce a light during the conductivity lab. On the other hand, Emerald Estates had a lot of phosphates and nitrates in their water sample. In Figure 5 it shows how they had 0.05 ppm of phosphates and 3.5 ppm of nitrates.…

about nitrates would affect Maria’s pregnancy very seriously. First of all, nitrate in water is undetectable, and without testing mean, it is colorless, odorless, and tasteless. So it is very necessary for water test if the household has infants, pregnant women, nursing mothers, or elderly people. Therefore, if the Juan and Maria were never checked the water supply since the livestock operations, it should be tested. The best ways to avoid everything is 1st Eat organic food. Synthetic nitrates…

30 minutes, the scientist noted the once clear liquid was now a dark, rich, blue aqueous Copper (II) Nitrate solution. While the solution at first appeared homogenous, the scientist noted the presence of 4 - 1mm small dark lumps, unreacted brass. From here, the scientist utilized the colorimeter to find the absorbance of this solution in collusion with the absorbance plot for Copper (II) Nitrate solutions of various molarities. From the linear fit of the Beer’s Law plot, calculations for the…
