The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3, Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product, Co(acac ·NO2)3. The exact mechanism of the reaction is unknown, however, it is believed to proceed as follows: 1) [pic] 2) [pic] Data and Calculations Table 1: Measurements of weights and melting point |†¦show more content†¦Some of the product was dark green, with a plastic-like consistency while some of the product was a lighter green, with a powder/paste-like consistency. Discussion The objective of this experiment was to synthesize Co(acac-NO2)3 using Co(acac)3 complex. This demonstrated that the reactivity of a ligand is changed when it is bound to a metal. The acetylacetone-Co3+ structure is similar to the structure of benzene, allowing for an electrophilic aromatic nitration of the central carbon. Copper nitrate trihydrate and acetic acid react to form acetyl nitrate, which then reacts with Co(acac)3 in ice water and sodium acetate to form a dark green oil. This oil was solidified using ethanol to form the final product, Co(acac-NO2)3. Analysis of the product showed the melting point to be 182-187 °C. Since this is lower than the literature MP, it was determined that the product was impure. 0.3510 g of the product was synthesized, a 76%Show MoreRelatedSynthesis of Co(Acac)31077 Words   |  5 Pagessubmitted: 05/09/05 Chem 2130-3 Experiment 3: Synthesis of Co(acac-NO2)3 Introduction In this lab, Co(acac ·NO2)3 is synthesized using the Co(acac)3 complex produced in Experiment 2.

These can be considered to be attached to the central ion by co-ordinate (dative covalent) bonds. The molecules or ions surrounding the central metal ion are called ligands. Simple ligands include water, ammonia, acetyl acetone and chloride ions. Ligand has active lone pairs of electrons in the outer energy level. These are used to form co-ordinate bonds with the metal ion. All ligands are lone pair donors.

Unmodified iron oxide magnetic nanoparticles have high surface/volume ratio, which cause magnetic dipole-dipole attractions that result in the formation of aggregates. The aggregation

Curriculum Development Interview. This Paper Will Summarize

Curriculum Development Interview This paper will summarize the information gained by interviewing a Curriculum Specialist in a specific school district in eastern South Dakota. How curriculum is used and who determines how it is used will be the basis of the interview. Other aspects will include what the district’s process is when adopting curriculums and finally how the teachers are effectively using it. Included will be a reflection piece that will include the positive aspects of adopting and developing a curriculum, along with concerns and issues that may arise. In conclusion, there will be a comparison on how curriculum is today compared to how it was used twenty years ago. Demographics of the School District In eastern South Dakota,†¦show more content†¦During these discussions, different companies will come in with their curriculums and demonstrate why they feel theirs is the best option. These companies will give different quotes, negotiate with the director, and offer free materials to support their cause. D. Tyler states â€Å"companies will always give more free things if you ask, including discounts on shipping† (personal communication, January 19, 2017). When researching different companies, the main thing the director researches is whether or not that company’s curriculum follows South Dakota Common Core Standards. It is very important that the curriculum materials follow a coherent method to teach the standards. Curriculum Adoption Process This particular district is on a 7-year rotation when adopting curriculum. Prior to adopting a certain curriculum, the district takes a year to study before a decision is made. During this year, different samples are received from different vendors that teachers are able to use in their classrooms, in addition, there are professional development opportunities where teachers are able to get together and assess the series using a rubric system the specialist has created. This way the teachers know if the curriculum is effective or not by implementing some of the samples in their day to day lessons. After this process is completed, the district chooses two or three companies who scored well among the staff.
