5. At 11:00 pm the second building collapsed. At midnight, with the fire threatening the facility's anhydrous ammonia tanks, an evacuation of approximately 3,000 residents within a 1/2 mile radius was ordered. By 3:30 am the fire had been pushed back from the area of the ammonia tanks and the evacuation was changed to an advisory. At noon, the MFD requested mutual aid (fifty volunteers responded) from surrounding communities to give MFD firefighters

SVN 3M The Nitrogen Cycle Name: Isabelle Rowe Go to the following website: http://nortonbooks.com/college/biology/animations/ch38a02.htm 1. What are the 2 forms of usable nitrogen? The two forms of usable of nitrogen are ammonium and nitrates. 2. What is the term used for this conversion process? This conversion of N2 (nitrogen) into NH4+ (ammonium) and NO3- (nitrate) is called nitrogen fixation. 3. Much of nitrogen fixation by humans

Urea cycle Introduction The task of urea cycle is to avoid the amassing of toxic NH4+. It incorporates nitrogen not used for biosynthetic purposes into urea, which serve as the waste nitrogen produce in mammals. Urea is the major disposal form of amino groups derived from amino acids, and account for about 90% of the nitrogen-containing gears of urine. Also urea cycle is accountable for de novo synthesis of arginine. The complete Urea Cycle is by far only in liver. However, some enzymes of the

Introduction What Is Diazotroph? Diazotrophs are bacteria and archaea that fix atmospheric nitrogen gas into a more usable form such as ammonia. A diazotroph is an organism that is able to grow without external sources of fixed nitrogen. Examples of organisms that do this are rhizobia and Frankia (in symbiosis) and Azospirillum. Types Of Diazotroph? Diazotroph are across bacterial taxonomic group (mostly in the bacteria and archaea). With a specific that can fix nitrogen may be strain do not fix

One of the possible systematic error that may occur in this experiment is that the hydrated (II) ammonium sulfate is contaminated as the iron (II) salt was left uncovered. The iron (II) salt was prepared by the lab assistant and the salt was left at the table uncovered for students to scoop the desired amount of salt they want. The iron (II) salt might be contaminated by dust particles and even saliva. This would cause the standard iron (II) solution to have less iron (II) salt in it and this means

In this experiment, groups were given two different unidentified substances with the goal of being able to figure out what chemical each substance was. Unidentified substance “2” was proven to be Tin (II) Chloride and the Unidentified substance “4” turned out to be Sodium Chloride. The conclusion that substance “2” was Tin (II) chloride could be proven due to the fact that it reacted with Zinc and Sodium Hydroxide. When Tin (II) chloride reacted with Zinc, it began bubbling. This occurred because

The synthesis of copper hydroxyl nitrate salt was started by adding 1.91 g of Na2CO3. H2O dissolved in 25 mL of deionized H2O onto 7.01 g of Cu(NO3)2.2.5H2O dissolved in 30 mL of deionized H2O. Then the mixture was heated at 45 ◦C continuously for 30 minutes even though there were some moments of temperature fluctuation at the beginning. After the mixture cooled to room temperature, it was filtered by suction filtration. Then the resulting copper hydroxyl nitrate precipitate was transferred onto

After identifying the first cation, the following procedures identified the second cation, which was barium or calcium. The second cation was identified by using the liquid portion of the solution mixed with hydrochloric acid and separated from the white precipitate, silver chloride after being centrifuged. Ammonium carbonated, which serves as to help confirm the presence of either barium or calcium cation, was added and stirred to this existing solution, causing the solution to become cloudy and

Hydrochloric acid is a colorless, clear, highly corrosive liquid that can cause burning. Hydrochloric acid is a very good industrial acid; it’s good for pickling iron and steel. Hydrochloric is found naturally in the stomach with the other gastric juices. Hydrochloric acid plays a role in the digestion of the food, and releasing enzymes in the stomach. Hydrochloric acid is found with the other gastric juices which are mostly potassium chloride, and sodium chloride. Hydrochloric acid is made up 5%

Introduction: There is a very big importance in knowing a compounds identification. Throughout history, there have been errors in the identification of compounds in items such as pet foods leading to deadly effects. Part one and two of the project will require students to use chemical tests to identify cations and anions. In an ionic compound, there are cations and anions. Through the identifications of cation and anions, students will discover the unknown ionic compound that is given to them.

Proteins are the most abundant molecules in cells, making up 50% or more of their dry weight. Every protein has unique structure and conformation or shape, which enables it to carry out a specific function in a living cell. Proteins comprise the complex muscle system and the connective tissue network, and they are important as carriers in the blood system. All enzymes are proteins, enzymes All proteins contain carbon, hydrogen, nitrogen and oxygen. Most protein contain sulfur and some additional

Amino acids are organic compounds that are the building blocks for proteins (Bruice). They are composed of a carboxylic acid with a protonated amino group and a hydrogen on the alpha carbon (Bruice). Amino acids have various side chains that provide proteins with great structural diversity, and in turn, functional diversity (Bruice). Amino acids can be divided into polar, non-polar, acidic, and basic (Bruice). The amino acids used in this experiment are Phenylalanine, Leucine, Lysine, and Alanine

As a young man, Ira Remsen was intrigued by science, leading him to perform an experiment that he saw in a textbook. This experiment involves a series of chemistry topics, triggered by the reaction that occurs between nitric acid and copper. The experiment involves an elevated flask, plug, a hose, and a container of water the set up is diagrammed below: Initially, place a copper penny in the flask then, standing by with the hose and plug, pour nitric acid into the flask and immediately seal. A

Perry Abstract: The purpose of this experiment was to determine the percent by mass of water in a hydrated salt as well as learn to handle a laboratory apparatus without touching it. The mass of water lost in grams for trials 1 and 2 are 1.7220g and 1. 2993g.For trails 1 and 2 the percent by mass of volatile water in hydrated salt came out

In performing these sets of experiments, in which we would drop a water/water solution onto the surface of a penny, we were trying to test and experiment the bonding qualities of water when made into a solution compared to when the water is pure. When we dropped pure tap water on to a penny, the water, instead of flowing and spreading out, stayed together in a single drop on the penny. We wanted to see how different substances affected this phenomenon. When we formulated our guiding question we

On Sunday, February 5th, 2012, at approximately 6:30 pm, I and my forensic team were dispatched to an arson fire scene at 8119 189th Street Court East in Graham, Washington. Upon arrival, I entered the rental home of Josh Powell which was entirely burned and damaged. As I walked through the residence, I found out the point of origin was from near the living room as I and my investigators found one empty gasoline can. The capacity limit was five gallons. It is to my belief that Josh Powell saturated

Safety is the number one consideration when it comes to jobs like welding. Welding can be very hazardous to a welder if he or she is not wearing the proper safety gear or taking the proper safety procedures. When welding a number of things could go wrong from explosions and gases and fumes to electrical shocks, burns and more. This paper will describe welding hazards and procedures that can be taken to avoid them. One of the main safety hazards of welding is fumes and gases. Many processes such

Electric weed eater does not come with much moving parts. The presence of less moving parts gives it an edge over gas weed eater because it makes it not to require much maintenance like the gas powered weed eater. In other words, if you buy this type of weed eater, you will not be spending much money on maintenance or repair. This does not mean that it does not spoil. It can spoil because it is a machine but the rate this happen is low when compared with gas powered weed wacker. Electric weed eater

Aquaculture in India Aquaculture is the cultivation of the natural produce of water (such as fish or shellfish, algae and other aquatic plants). Mari culture is specifically marine aquaculture, and thus is a subset of aquaculture. Some examples of aquaculture include raising catfish and tilapia in freshwater ponds, growing cultured pearls, and farming salmon in net-pens set out in a bay. Fish farming is a common kind of aquaculture. India offers a huge potential for aquaculture development. The
