Hydrogen peroxide

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…

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…

example: Highly pure silicon for computer chips is produced through a displacement reaction. In this reaction, hydrogen reacts with silicon tetrachloride to form hydrogen chloride and release silicon. 4. Double displacement reactions: Double displacement reactions are those in which two compounds exchange ions to form two new compounds. For example: In the reaction of copper sulphate and hydrogen sulphide, copper sulphide and sulphuric acid are…

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…

1.4 Effect of Microcrystalline Cellulose (MCC)Type Formula F12 was utilized to study the effect of changing the type of MCC(Avecil PH-101 ) as a carrier material instead of (Avecil PH-102) in F8 on the dissolution behavior of the prepared Zolmitriptan liquisolid ODTs. Although the DT of formula F12 (79 sec.) was greater than F8 (48 sec.) as in Table(18),the dissolution behavior of the formula F12 was faster than F8 as in Table (18) and Figure (48), this difference was non…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

The unique composition and purity of as-deposited SnS2 thin films prepared with different precursor solution volumes from 5 ml to 25ml were determined by EDX analysis as shown in fig 5, which brought out the presence of Tin and Sulfur as elementary components. Two different peaks were observed in the spectrums from fig 5 relevant to the tin and sulfur. The EDX spectra show that the weight percentage for the film prepared at the precursor solution volume of 5 ml is 36.8% and 63.2%, which is…

Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400…

temperature of about fifty degrees Celsius, and 100g of fine powders of antimony sulfide are added in small amounts periodically to the heated mixture. After all of the crystals of antimony sulfide have been added to the mixture and evolution of hydrogen sulfide has subsided, the temperatures are adjusted to higher levels gradually until the resultant solution starts to boil (Karl‐Heinz and Magnus 20). It is left to boil for an hour, adding boiling water periodically as it evaporates which…
