In this work‚ the Fe3O4 NPs were synthesized by a co-precipitation method. The prepared Fe3O4 particles were dispersed well in water and stay stable for several days. FT-IR spectra of Fe3O4‚ mercaptosuccinic acid and mercaptosuccinic acid functionalized Fe3O4 are shown in Figure 1(a-c)‚ respectively. In Figure 1a‚ the sharp band at about 585 cm-1 corresponds to the characteristic Fe–O vibration peak and the bands at around 3420 cm-1 are due to the stretching vibrations of the hydroxyls (–OH) on the

Abstract The experiment was conducted‚ which metals manganese (Mn3+)‚ Cobalt (Co3+) and Copper Cu3+ was prepared and acac complexes where also obtained. Recrystallization was performed of which Mn(acac)3 ‚Co(acac)3 and Cu(acac)3 was obtained at percentage yield of 32%‚ 85.6% & 92% for each of acac’s. TLC was performed which results deduced unknown mixture both contained manganese and cobalt since it had the same Rf vaues. Experiment aims The aim of the experiment was to prepare metal

The element I chose is Sulfur. Sulfur’s symbol is S‚ and it’s in the Chalcogen family. Sulfur has a lot of roles to play in our bodies. It’s also one of the abundant elements in our bodies with a mass percentage of 0.2. Sulfur’s atomic number is 16‚ and its Mass number is 32.066. In addition‚ Sulfur is a non-metal. Sulfur has multiple physical and chemical properties; one of the physical properties is that Sulfur is insoluble in water. A chemical property for Sulfur is that it’s a very reactive element

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and

al Chain Reactions: Bromination of Arenes Introduction The purpose of the bromination of arenes was to determine the different reactivities of different hydrocarbons with different hydrogen atoms when reacted with bromine under free-radical substitution. The time it took for the bromine color to disappear was used to determine the order of reactivity of the different hydrocarbons. Data and Results The data of the 10 hydrocarbon tubes and the 2 control tubes with bromine and dichloromethane in
