Nitrate

media for digital materials are vulnerable to deterioration and catastrophic loss, and even under ideal conditions they are short lived relative to traditional format materials. The archivists have been battling with acid-based papers, thermo-fax, nitrate film, and other fragile media for decades. They are the first reusable media and they can weaken rapidly, making the time frame for decisions and actions to prevent loss is a matter of years, not decades.  More challenging than media fragility…

formed a dark blood red liquid. Before they were mixed, the two liquids had a mass of 3.43 grams. When mixed, they ended up with a mass of 3.33 grams. This was because some of the liquid from the tubes possibly evaporated. We then mixed a barium nitrate solution, a white powdery liquid with an iron sulfate solution, another clear liquid. Before mixing, the total mass was 3.2 grams. After mixing the two substances, the combination of the two liquids ended up looking very powdery. We then mixed…

3.4.2.1 Test for milk:- 1. Determination of SNF in milk AIM: - to determine the SNF of milk Apparatus: - lactometer jar, lactometer and thermometer Principle: - It is calculated by using lactometer method. Procedure:-  Warm the milk sample to 40 to 45oCand maintain at this temperature till 5 min.  Mix the contents by rotating and inverting the bottle, taking care to avoid the formation of air bubbles.  Cool the sample to 15.5oC  Invert the sample bottle 2 to 3 times; pour enough milk into…

of oxygen causing fish and other marine life to sadly die. Because of the toxins created by red tide, skin irritations and respiratory trouble may occur in humans. Red tide is not a man-made virus for marine life, but it can be fueled sometimes by nitrate pollution and sewage dumped by cities causing the red tide to last longer. Florida’s marine life and beach-based businesses are at stake because of sewage and fertilizer run-off. If Florida does not…

Congestive heart failure effects approximately 5.1 million Americans, with about 670,000 new cases diagnosed each year (Davidson,2015). In 2009, one in nine deaths were contributed to heart failure (Davidson,2015). The expectancy life span after being diagnosed is approximately five years. It effects mostly the elderly over the age of 65. CHF is a chronic disease that over time gets worse because of the weakening of the heart, increased workload, which reduces the amount of oxygenation that can…

During this nation’s most costly war, both sides, the Union and the Confederacy, took advantage of brave women willing to support their causes. These women participated in various courageous acts, and succeeded in altering the course of the Civil War. Sarah Emma Edmonds was one of about 400 women who succeeded in joining the Union or Confederate army. From her young life in Canada to her disguises and service in the Union Army, and even to her peaceful post-war life, Edmonds has illustrated a…

The American dairy industry is constantly growing and is always in a state of flux. With the milk market expanding to places in every corner of the globe, American dairy farmers strive to suffice the needs of an ever growing world population. The American dairy industry provides over 1,500,000 million jobs nationwide and generates billions in taxpayer dollars. It is a well-known fact that the dairy industry contributes immensely to the economies of thousands of communities, regions, and…

This lab was conducted to find the key differences between the quantity of heat (q) and ∆H of a substance. Different masses of substances CaCl2 and NH4NO3 were dissolved in water to see how changing mass impacts the q and ∆H of a substance. When the two substances dissolve, they become ions. CaCl2 dissolves in a reaction of: CaCl2 Ca2+aq + 2Cl1-aq while NH4NO3 dissolve in a reaction of: NH4NO3 NH41+aq + NO31-aq . As shown in these reactions, when ionic compounds dissolve in water, they break…

Fresh Water Problem and How to Solve It Water is a natural energy that comes from the earth and all of the living being on earth are depend on the water, without water humans and animals are dead. 75% of the surface of the earth is covered by the water, despite the amount of the water on the earth is abundant the problem is the amount of the fresh water that we have. About 97.5% of all water on the earth is salt water, this means that we only have 2.5% of fresh water left. Approximately 70% of…

synthetic nitrogen has fertilized not just the farm fields but the forests and oceans, too, to the benefit of some species (corn and algae being two of the biggest beneficiaries) and to the detriment of countless others. The ultimate fate of the nitrates spread in Iowa or Indiana is to flow down the Mississippi into the Gulf of Mexico, where their deadly fertility poisons the marine ecosystem. The nitrogen tide stimulates the wild growth of algae, and the algae smother the fish, creating a…
