Editor's Notes
- #2 Anibal
- #4 Abneil This synthesis consist in the mix of two solids. This is an important study because it lets us synthesize new compounds to characterize and to evaluate new properties po
- #5 Anibal Superconductors have high capacity to conduct electricity such as silicon as the word expresses. Inside of your computer or maybe even your television set are little black boxes called chips. Scientists flatten silicon crystals into little circles called wafers. These wafers are then stamped with the image of a computer chip.
- #6 Here we have the sample of a work related to what we did, this was done by Koscieslky and collaborators and they managed to characterize physical and chemical properties of a thorium derived compound
- #7 Ramon Quaternary: 2 metals, chalcogen and intrinsic Oxygen Ternary: 2 metals with Intrinsic Oxygen
- #8 Ann Redox occurs Important factor : We do not know what combination or quantitiy we need to form crystals, Difficult because the combinations are endless Predictions are what make this proyect so challening
- #10 Anibal Similar elements to have the same melting point and a constant heating curve during experimentation
- #11 Ramon 1) The element was selected and determined the mass of each reactant by calculations. 2) First, we have a silica tube of 4 feet. Then, we have 1 feet. Second, the feet divided into 6” with the oxygen acetylene torch. 3) The Carbon Coating we administer 1 drop of acetone to the silica tube and then burn it in the bunsen burner. It was repeated 2 more times. We use the Acetone to have the crystals separated of the tube. The purpose is that the light do not react with the compounds.
- #12 Abneil 1)Transfer reactants with the specific amount calculated to react in terms of their ratio 2)Tubes into furnace Lisa to melt one of the solids to make 3) Analyze in dissecting
- #13 Ann As mentioned previously we need reactants close to melting points between each, For each reaction heating , be it ternary or quaternary it is neccesary to build a heating curve This heating curve will determine at which temperature compounds will mix At this constant temperature the reactants will mix in their liquid states. Cooling produces crystals and a faster cooling will not give enough time for crystal growth

- #16 Ramon In Chemistry, powder are tiny particles that have crystal structure. In the images of each reaction we saw powder. Powder: tiny particles that are above the floor and in the air. (Dictionary)

- #20 Abneil We did not obtained the kind of crystals we were expecting. We obtain Oxide Powder.
- #21 Ann Unfortunately, we had various limitations Not much time to make 16 reactions, only achieved 8 of them. The quaternary was not possible since every reaction had to be exposed to about 7 days or more Intrinsic oxygen could not be calculated.
