When a hydrogen atom of an alkane is replaced by halogens, they become an alkyl halide compound which can also be called haloalkanes. There are two types of reaction within the alkyl halides. When another atom replaces the halide ion, the reaction becomes a substitution reaction, and when the halide ion leaves with another atom or ion, it becomes an elimination reaction (Weldegirma, 2015). The substitution reaction can be divided into either electrophilic substitution or nucleophilic…

Atoms are the simplest form of matter. On Earth matter can be a solid, liquid, or a gas. The atoms that create the states of matter also create elements. Currently, there are organized on a chart known as the periodic table, one such element is Germanium. In fact, Germanium has a symbol known as Ge. A symbol is a shorter way to represent the element. All elements have a symbol, atomic mass, atomic number, and a number of protons, neutrons, and electrons. Germanium’s atomic mass is 72.64, this…

carbon atoms in an alkanol is increased, then the alkanol containing the longest carbon chain will have a higher heat of combustion, because as there are more carbon atoms, more energy will be released as a result of the breaking of the covalent bonding and the forming of bonding as the final product. INTRODUCTION Fuels are hydrocarbons…

and to help identify a substance. The smallest particle of matter is the atom. An atom has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon atoms. An example of an organic compound is proteins, fats, carbohydrates,…

essentially make fat tissue, which stores energy as fat. 40. hydrolysis/dehydration Hydrolysis- Hydrolysis is the reaction with water. It is a chemical procedure in which an atom is severed into two sections by the expansion of a molecule of water. One piece of the parent particle picks up a hydrogen particle (H + ) from the extra water atom. The other gathering gathers the rest of the hydroxyl gathering (OH − ). Dehydration- is the reduction of water level in the body of an organism. 41.…

energy is always positive. A light wave is made up of these photons, meaning that are the composition of light itself. With this in mind, photons can hit each other, and do so very frequently. When photons bump into other atoms, much of their energy can get the electrons within those atoms to move much faster. These electrons do not want this additional energy, thus they give off heat so that they may return to stable conditions, and this is why we feel…

where the positive charge was the flesh of the watermelon and the electrons were the sects. a) J.J. Thomson who discovered the electron in 1897, proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus in order to include the electron in the atomic model. b) In Thomson’s model, the atom is composed of electron surrounded by a soup of positive charge to balance the electron’s negative charge like negatively charged “plums” surrounded by positively charged…

The nuclear model of the atom consists of mostly empty space, the center of the atom is called the nucleus, the nucleus contains the protons, which have a positive electric charge, along with the neutrons, which have a neutral charge and is slightly heavier in mass when compared to a proton. Along the outer rings of the atom the electrons orbit, the electrons have a negative electric charge, as well as the smallest mass out of the three. “The nuclear forces” is a common name used to describe the…

Copper is a transition metal with the chemical symbol “Cu”. Like all atoms, it is composed of protons, neutrons, and electrons. Protons are positively charged subatomic particles with a relative mass of one. Neutrons are neutrally charged subatomic particles with a relative mass of one as well. The nucleus contains both the protons and the neutrons. Electrons are negatively charged subatomic particles with a relative mass of 1/200. Though protons and neutrally differ drastically in size, their…

structure of Silicon Carbide and its properties was under the equilibrium condition, which means the location of each atom is restricted at its lattice site. The vibration of atoms about their equilibrium sites will be considered in this chapter. The fundamental reason of this vibration is thermal and the lowest achievable energy (i.e. zero-point energy). The forces acting on atoms tend to always make them return to the equilibrium position. The relation between atomic forces and thermal motion…
