Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly…
Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…
Principle components of Rankine cycle: The four basic components of Rankine cycle are shown in figure 1 each component in the cycle is regarded as control volume, operating at steady state. Pump: The liquid condensate leaving the condenser at the state 1 is pumped to the operating pressure of the boiler. The pump operation is considered isentropic. Boiler: The heat is supplied in the working fluid (feed water) in the boiler and thus vapour is generated. The vapour leaving the boiler is wther…
Paragraph 1 Iron phosphate structure with a symbol of FePo4, has crystal structures of FeO4 and PO4 as its tetrahedral links. There would be changes of this quartz type that can be determined by the neutron poly difraction between 294K and 1073K, according to Z. Kristallogr. While structural parameters of the iron phosphate depends on the temperature, whereby iron phosphate would be a beta-phase from an alpha-phase when temperature increases from low to high. Irregularity would also be…
- To Study about types of chemical reactions such as combination, decomposition, displacement and double displacement. - Find out about oxidation and reduction (redox reactions). II. Definitions: 1. Combination reactions: Combination reactions are reactions in which two reactants combine to form one product. For example: when a metal undergos a combination reaction with oxygen, a metal oxide is formed. 2. Decomposition reactions: Decomposition reactions are those in which one compound…
III. RESULTS AND DISCUSSIONS: A. Characteristics of Aluminum-Graphite composites and the in-situ reaction To examine the reaction condition of carbon flakes and Al powders, 4 wt. % carbon flakes were added to Al powders. Fig. 1 shows the DSC plot obtained during heating and cooling of the green compact from room temperature to 750 0C and from 750 0C to room temperature at a heating/cooling rate of 3 0C /min under argon gas atmosphere. From the DSC heating curve it is evident that the total…
Phase 2 – Agarose Gel Electrophoresis 1. Obtain our four H, E, L, and P labeled micro tubes and place them on ice. 2. Set the micro pipet to 2.0 ul. 3. Transfer 2.0 ul blue dye to each of the four H, E, L, and P micro tubes. 4. Mix the four micro tubes by using this two-step method: * Place each tube briefly on the vortex to get the components to collect at the bottom of the micro tubes * Pulse spin the four micro tubes in the centrifuge to mix all of the components completely. 5.…
When the drug within the liquisolid system is completely dissolved in the liquid vehicle, it is located in the powder substrate still in a solubilized state. Therefore they show improved release rate ,Thus, its release is accelerated due to its markedly increased…
According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…
alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapor phase [2]. Chemical vapor deposition belongs to the class of vapor-transfer processes. Differ from physical vapor deposition, CVD process includes chemical reactions. In the process, gaseous material change in to solid which means the process is…
