barrier that prevents lead from leaching into the water”(Schock). this protective scale can make up of ninety percent lead it’s using lead to protect people from lead against lead. This method prevent erosion from happening. Water utility add a chemical that help build the scale and to protect the water. This method is so important that EPA lead and copper rules require that city with over fifty thousand people to have corrosion treatment in place. However Flint water plant did not have any of…

Valuable, colorful, and enriched with a unique history are three phrases that describe many things. However, all three combined only seem to describe Birthstones. Birthstones are amazing objects that affect our economy in many ways. More importantly, birthstones have a deep connection to chemistry and science. Due to their chemical properties, birthstones can also be used for medicinal purposes and healing techniques that have helped humans throughout time. Overall, birthstones contain many…

universal thing; water. It wasn’t until Democritus and the Atomist until philosophers began to rationalize about small particles called atoms as the things that make up the universe. As time approached the 18th century, advances in the scientific method gave rise to developing processes to examine the composition of gas molecules and the molecular weights of the atoms that make up chemical compounds. Throughout the rest of 18th century, investigation into chemical species continued and soon…

– 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…

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 Shakespeare’s The Tempest with the goal of evaluating the traditional and nontraditional elements of the show. Subsequently, the similarities and differences between CLC’s the Tempest and Carthage’s the Breathe of Stars will be considered in order to generate…

John Dalton was an English chemist, physicst and meterologist. Might be familiar with "Daltons Law of Partial Pressures" which is a law still used today, or "Daltonism" also reffered to as color blindness. Dalton was born in Eaglesfield, England on September 6th, 1766. He lived a great life until his death on July 27, 1844 as he died of a stroke in Manchester, England. John Dalton was born into a strong Quaker family (family thats known as "Religious society of friends". John had 2 survivng…

Both the tables and chairs are secure and sturdy enough to lean, yet they are able to slide under too much pressure. The lighting is distributed evenly without being too dim or too bright. There is not an area set aside in case a child becomes over-stimulated. Voices are heard throughout the classroom without echoes. The room is only noisy during center time and when a child is upset. It is easy to listen and focus on a child next to you unless a child was being distracting by throwing a…

In Co(NH3)6Cl3, since the complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low…

1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…
