Fig.7, shows that, the insulator behavior of the PVA for pure PVA. But, with increasing the time of reaction there is an improvement in the electrical conductivity of the PVA-Ag nanocomposite films. Fig.7 shows that, the (I–V) characteristic of the samples, and the inset of Fig. 7 shows the relation between the conductivity and time of reaction. Then, the dc conductivity was calculated at the (voltage = 10 V) using the relation. (S/cm) Where (d) is the sample thickness, (A) is the area of…

Phenacetin and Tartaric acid was later found to show the effect an impure substance has on temperature. Melting point range for unknown three that was lastly tested was matched to Acetaminophen by comparing their melting points. Introduction: Melting point is loosely defined as the temperature at which a solid becomes a liquid. In chemistry, melting point, also recognized as the liquefaction point, refers to the temperature at which the solid and liquid phases of a compound are equal. Melting…

done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume of the cell expands with…

WRITING EXERCISE PARAGRAPH I FePO4 is a type of -quartz, and when the temperature is relatively low, FePO4 still has the tetrahedral structure as seen in Figure 1. The Fe-O-P bridging angles are more similar between the FePO4 and -quartz. Change in the cell parameters become more significant between temperatures of 294K and 1073K, and it slowly acquires an octahedral structure as the temperature increases. When temperature reaches 980K, the compound transitions and the tilt angles decrease…

Raj Bose IB Chemistry HL Period 4 15/10/2014 Research Question: How does increasing the concentration of copper (II) nitrate solution in a voltaic cell affect the voltage produced? Variables: Variables Description of the variable Method of controlling variable Independent Concentration of copper (II) nitrate solution used in each trial of the experiment. N/A Dependent The voltage being produced by the two electrodes which is measured by the voltmeter N/A Controlled Concentration of the zinc…

management 2.4.1 Calories A calorie is the unit used to measure the energy-producing value of food. Theoretically, calorie is characterizes as a unit of heat measurement, in nutrition and the kilocalorie is the amount of heat required to raise the temperature of 1kg water through 1˚c. Another definition is that calorie is a unit of measurement that determines the amount of heat released in a food during metabolism. It states the energy value of a food calorie (cal) or kilocalories (kcal). The…

Emulsions are two-phase systems, a mixture of two or more liquids that are normally immiscible. There are two phases in the system, in which one is the continuous phase and the other one is the dispersed phase. Types of emulsions [38] Oil in water (o/w): in which oil is the dispersed phase and water is the continuous phase. Water in oil (w/o): in which water is the dispersed phase and oil is the continuous phase. Emulsions have a cloudy or opaque appearance because particles scatter light…

polyurethane graft and another with a silicon rubber graft. The computations were done under a pulsatile flow. Both cases were computed under maximum peak pressure as mentioned in the method section. The flow volume rate is expressed by integrating on surface as followed: Q=∬_A^ ▒v.dA (5) By integrating flow volume rate in time the whole volume was examined on three different…

The sun was up to death. It was really hot. I felt as if the only to survive such a day was to sweat a lot. Of course, I was sweating. A lot. My stomach was aching. I have not eaten since that morning. I have spent almost two days just eating some bread with butter. Just a day before like this, I was notified by the U.S. Embassy Brazzaville that I failed my TOEFL test. The Fulbright Fellowship was no longer within my reach. The burden of the pain was still running all over my body. My dream was…

The concentrations of difference between the membrane phase and feed phase based on the mechanism of mass extraction. In the case of feed solution represented radioactive simulated waste solution and dissolved in 0.5M HNO3. In the feed phase decreasing with H+ concentration. pH values at 2.5 into 5.5 in the feed phase. Fig,s(5a-5c). Shown the effect of hydrogen ion concentration in the feed phase and studied of pH range 2.5-5.5 for 0.5M HNO3. Stripping solution of 0.05M of EDTA. Initial…
