TABLE 1 - Particle Size Range (micrometers).5 3. RESULTS AND DISCUSSIONS Experiment A shows that the compound present in the dust sample is Sodium Nitrate. Experiment B shows the dust is inhalable and can directly get to the lungs. From the oxidation state of nitrogen, Nitrate is the most oxidized form of nitrogen present in the environment. It accounts for the majority of the total available nitrogen in surface waters (Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong …show more content…
It is produced also by the reaction of ammonium nitrate and sodium hydroxide, sodium bicarbonate or sodium carbonate. NH4NO3 + NaOH → NaNO3 + NH4OH NH4NO3 + NaHCO3 → NaNO3 + NH4HCO3 2NH4NO3 + Na2CO3 → 2NaNO3 + (NH4)2CO3 Sodium Nitrate (Nitratine) is Isostructural with Calcium Carbonate (Calcite). This means they have similar chemical structures. In terms of their crystal nature, they are also said to be Isomorphous. Sodium Nitrate is called Nitratine when it is in a mineral state. 3.3. USES OF SODIUM NITRATE Sodium Nitrate is used in manufacturing smoke bombs. The sample preserved in a small water bottle deformed the bottle and expanded it. This proves it is viable product in the manufacture of gun powder and smoke bombs. It is used in making ceramics and glass. This compound can be used in meat preservation. In both organic and inorganic states, it is used in fertilizer production. 3.4. CALCIUM CARBONATE Literature studies proved some traces of Calcium Carbonate in the sample. Its natural means is marble or quarry. Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite (Kearey, 2001).

Results The lab experiment was done in two parts, one with the NAND, NOR, XOR and Hex Inverters and the other with a 7483 full adder gate, both will verify the truth table when two input bits and a carry are added together. The circuits were built by examining the 1 bits through a K-Map to create a Boolean expression for the sum and carry. The Boolean expression for the sum was A⊕B⊕C and the carry as AB+BC_in+AC_in. From these two expressions, we notice that we must use two exclusive-ORs gates in the sum inputs for A, B, and C. For the sum, we have to use NOR and NAND (the only available gates from the lab manual).
For most sequences at position 4 and 5 we observe only the nucleotides G and T, respectively. There may be rare cases where other nucleotides may also be found. To consider such observations, we need to do a process called additive smoothing or Laplace smoothing to smooth the categorical data. [9] In this case, we add 4 sequences: AAAAAAAAA, CCCCCCCCC, GGGGGGGG, TTTTTTTTT.
I need to find the area of rectangle ABCD. I know that ABCD is a rectangle with diagonals intersecting at point E. Segment DE equals 4x-5, segment BC equals 2x+6, and segment AC equals 6x. I predict that To find the area of rectangle ABCD I need to find out the base and height of the rectangle. The first step is to find what x equals. Since I know the intersecting line segments AC and DB are congruent that means when I times the equation 4x-5 for segment DE by two it will equal the equation 6x for segment AC.
Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

Suppose we have a single-hop RCS where there is one AF relay that amplifies the signal received from a transmitter and forwards it to a receiver. Assume that the transmitter sends over the transmitter-to-relay channel a data symbol ${s_k}$, from a set of finite modulation alphabet, $S={S_1, S_2,ldots,S_{cal A}}$, where ${cal A}$ denotes the size of the modulation alphabet. The discrete-time baseband equivalent signal received by the relay, $z_k$, at time $k$ is given by egin{equation} z_k = h_{1,k}s_k + n_{1,k},~~~~for~~k=1,2,ldots,M label{relaySignal} end{equation} where $n_{1,k}sim {cal N}_c(0,sigma_{n1}^2)$ is a circularly-symmetric complex Gaussian noise added by the transmitter-to-relay channel, $h_{1,k}$ denotes the transmitter-to-relay channel, and
Using the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

The test subjects will all set alarms on their smartphones for approximately 6, 8, and 10 hours after the subjects’ enter the resting period (Subjects may wake during the resting period for the bathroom, but they must not stay awake for more than ten minutes at a time to prevent as much deviation as possible.). 3.

Farmers turned to fertilizer, which contains Nitrates. Nitrates also known, as NO3 is a natural compound made of oxygen and nitrogen (Chern, 1999). Nitrates can be found in the air, soil, water, and plants (Johns & Yaremcio, 2004). Much of the nitrate in our environment comes from decomposition of plants and animal wastes (Partnership For Environmental Education and Rural Health, 2015).
Nitrogen, in bonded form. is part of protein. Deca Durabolin causes the muscle cell to store more nitrogen than it releases so that a positive nitrogen balance is achieved. A positive nitrogen balance is synonymous with muscle growth since the muscle cell, in this phase, assimilates (accumulates) a larger amount of protein than usual. The same manufacturer, however, points out on the package insert that a positive nitrogen balance and the protein building effect that accompany it will occur only if enough calories and proteins are supplied.
2.4 Band Division and Energy Computation: The power spectrum of the signal is multiplied by magnitude response of set of 33 triangular band pass filters and in the range 300Hz-2000Hz. Sub-bands are formed by using the logarithmic spacing. The positions of these filters are equally spaced along the Mel frequency, which is related to the common linear frequency f by following formula: Mel (f) = 1125* ln (1+f/700) (3) Mel frequency is proportional to the logarithm of linear frequency and which is close to the human perceptual system. 2.5 Sub Fingerprint Generation:
Abstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
The body naturally creates this chemical, but during exercise it depletes and it takes a while for it to fully replenish. This ingredient can help users feel more energetic and enjoy enhanced recovery in between workouts. Niacin (also known as vitamin B3) is a naturally occurring amino acid that assists the body in producing nitric oxide during physical training. This ingredient is known to replenish nitric oxide levels, and assist the oxygen-flow and delivery to the muscles being
