sources. Fire involving large amounts of material should not be approached individual containers may rupture abruptly causing ‘fireball’ effect. Fire-fighters should wear self-contained breathing apparatus and full protective clothing when fighting chemical fires. Use water spray to cool nearby containers and structures exposed to fire. 5. Accident Release Measures In case of spill, do not blow material. Sweep or gather up material and place in proper container for disposal.…

Our initial investigation of the asymmetric Mannich reaction of indole 2a with phenyl α-amidosulfone 3a is summarized in Table 1. The effect of catalyst structure on the reaction outcome was first investigated at 10 mol% catalyst loading in toluene (Table 1, Entries 1–5). As we expected, based on our knowledge of the catalytic performance of chiral oligoEG 1,[7] the ether chain length (Entries 1–3) as well as suitable acidity of the phenolic protons (Entry 2 vs. Entries 4 and 5) are critical for…

that make up chemical compounds. Throughout the rest of 18th century, investigation into chemical species continued and soon experimentation gave rise to laws and theories. One of the most…

– equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…

In March of 2016, Carthage College staged a new production entitled the Breath of Stars, which was advertised as a modern adaption of Shakespeare’s the Tempest. In the same month, the College of Lake County offered a traditional performance of the Tempest, which served as an excellent means by which to evaluate the relative proximity of Carthage’s production to Shakespeare’s original text. This essay will begin with a detailed description of the College of Lake County’s production of…

All the materials were purchased from Sigma-Aldrich and used as received unless otherwise stated. Reaction (1) How to make Sodium Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium…

The role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…

In A Doll’s House, by Henrik Ibsen, people today can clearly see how Torvald mistreats his wife Nora. He treats her like a pet and calls her by little nicknames that are not appropriate for someone such as your wife. For example in the opening scene he says to her, “Is it my little squirrel bustling about?”(Ibsen), this is something people today find to be completely sickening but then it was a thing that was common and accepted. During the time it was written people acted in the exact…

and leave one at room temperature. Allow the tubes to sit for a while, then compare the tubes and record any differences. If there is enough time, allow the tubes to warm/cool down to room temperature and record any observations. Dispose of the chemicals into the proper…

earth`s surface. Chemistry can relate to chemical reactions, one of the chemical reactions that occur is the creation of acidic rain. It can also relate to sublimation after the sinkhole occur, and to the rocks in a sinkhole and what they 're made of. One of the chemical reactions that occur that is based upon hydrogen and carbon dioxide is “H2O(l) + CO2 9(g) -> H2CO3 (aq)’’ (Brian Rohig). The outcome of this equation is acidic rain. In chemistry we use chemical equations to show how…
