Lithium-ion battery

Different solvents need different amounts of energy to break their bonds, as they are made of different ions. • Temperature of the water. The higher the temperature of the water at the start, the bigger the energy changes in dissolving when it is exothermic. The factor that I will be looking at for this experiment is how the mass of solvent effects the temperature…

equals the total mass of the products. During a chemical reaction, the atoms/ions of the reactants are rearranged to form new products. Thus, chemical equations must always be balanced, with the same kinds and numbers of atoms/ions and mass on both sides of the arrow, meaning that the combined mass of the sodium hydroxide and carbonic acid, and the combined mass of the…

Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

solution has a sulphate ion present (4). Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well. HCl Test Fig 5. If HCl is present in the solution, bubbling and a strong smell of ammonium should be present. Using the remaining test tube, add 0.1 ml of HCl into the solution. Record your findings. Record Conductivity using Conductivity Meter. Flame Test Fig 5. Flame Tests are used to identify the presence of a small number of metal ions in a compounds.…

raised depends on how much of the solute there is. This makes the water dilute which means that most of the water molecules are at the bottom and few can escape. This is known as reducing vapor pressure of water. Table salt breaks into a sodium ion and chloride ion, so there are two particles. Sucrose would remain as one particle. (Your Mother Was a Chemist. (n.d.). Retrieved from http://kitchenscience.sci-toys.com/boiling_freezing_pressure). The question that this research helps answer is that…

Paragraph 1 For α-Quartz, its lattice symmetry is trigonal, and for β-Quartz, its lattice symmetry is hexagonal. For α-FePO4, its space group is P3121 and thus its lattice symmetry can be inferred to be also trigonal, just like α-Quartz. Similarly, β-FePO4 space group is P6422 and its lattice symmetry can be inferred to be hexagonal, just like β-Quartz. Although the chemical structures of quartz and FePO4 are different, with quartz having a formula of SiO2, they can actually be in the same…

They offer the specificity required to separate similar compounds from each other, such as separating polymers in plastic waste streams. Batteries:- They can replace water as an electrolyte in batteries. They are prefer because of their low vapor pressure. Their minimum electrochemical capacity is 6 volts as compared to water which is 1.23 volts. Ionic liquids can act as dispersing agents in paints to enhance finish…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…

Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate covalent bond is a covalent bond in which one atom (i.e., the donor atom) gives both electrons. This type of bonding is different from a normal covalent bond in which each atom supplies one electron. • If…
