Lithium-ion battery

In the Bay Back Battery Simulation, I was tasked to use strategic innovation to earn profits for the division of the consumer electronics manufacturer. As the President of Back Bay Battery, Inc., I was responsible for distributing funds for two types of batteries produced by the firm. Nickel Metal Hydride (NiMH) accounted for 80% of revenue for the firm while Ultracapacitor batteries (UC) only made up 20% revenue (Christensen & Shih, 2012). The company primary products covered portable power…

am hoping to solve is why are they so helpful. Why are they so important to the human body. The definition of an electrolyte is “any fluid that conducts electricity, such as this new saltwater solution, is known as an electrolyte solution; the salt ions of which it’s composed are then commonly referred to as electrolytes”(Nate Morrow 2012 pg 1). “There are several common electrolytes found in the body, each serving a specific and important role, but most are in some part responsible for…

Precipitation reaction, or otherwise known as double-replacement reaction, is one of the three common types of chemical reactions along with decomposition and combustion. A simple definition for the precipitation reaction would be “atoms from two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid…

It did this because the chlorine ion of HCl was able to bond with silver or lead, leaving the other cation in the liquid solution that was decanted and set aside for Part B.1 In Step 5, the sample with either silver or lead was heated in a water bath. This step was essential as heating the solution broke any ionic bonds within the…

The positive Na+ ions were attracted to the oxygen (negative) end of the water molecules, and the negative Cl- ions were attracted to the hydrogen (positive) end of the water molecules. As an end result, the ionic bond between the sodium and the chloride was broken. CuSO4(s) ⇔ Cu+2(aq) + SO4-2(aq) Like the sodium chloride, the copper sulphate was split into its individual ionic components. The positive Cu+2 ions were attracted to the oxygen (negative) end of the…

Title Determining the Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound.…

3.2. Molecular Electrostatic Potential (MEP) surface of Pyrazolooxazines. The correlation between the molecular structure and the physicochemical property of molecules, including biological molecules and MESP-based drugs, to distinguish electron rich zones (electrophilic attack) from electron-poor ones (a nucleophilic attack) 16, 17. We represent in this study the molecular surface of the electrostatic potential (MESP), the electrostatic potential (ESP) and the electron density (ED). MESP is a…

Paragraph 1 Sphalerite and wurtzite are the two polymorphs of Zinc Sulphide (ZnS). Sphalerite follows the space group F-43m, wurtzite is of the space group P63mc, and both polymorphs have the same formula of (Zn, Fe)S. The crystal chemical relationship between the two can be discussed by looking at the capability of transformation between the two polymorphs, known as polymorphism. This is due to the same SnS4 polyhedral found in both. Yet even though this is so, the two differ when we look at…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. FePO4 is also known as Iron (III) phosphate. Iron (III) phosphate is an inorganic compound. Most of the FeP04 has the structure of α-quartz which is α-FePO4. It has a tetrahedral molecular geometry. α-FePO4 is present at pretty low degree Celsius. It is also a transition metal as it is in the d-block in the periodic table. It can be studied at many different temperature which range from 294K to…

In Fig 4 pore size distribution profiles of the Y and MY is observed. By the BJH method, which uses desorption branch of the nitrogen isotherm in order to calculate the pore size distribution and the adsorbed volume[12], the pore size in the range of only 1.4 nm could be seen in Fig. 4a. Presence of various distribution of pore size is the manifest of the related BJH of the MY zeolite in Fig. 4b. As can be seen there are the pore size distributions from 1.2-6 nm in which the pores in the range…
