The stories Conducting Solutions, Energy Story, and the video Hands-On Science with Squishy Circuits have all helped me learn a lot more about electricity. The purpose of these sources were to help the reader to understand and inform the reader about how electricity is made. It also showed how easy it is to make electricity. These three sources have many differences and similarities but they all serve the same purpose. In the video Hands-On Science with Squishy Circuits it talks about how easy…

Pentane and Diethylamine have many similarities, but they also have their differences. Pentane comes from the Greek word pente meaning “five” as the atom is comprised of five carbon atoms as shown in the formula C5H12. Some characteristics of the molecule is that it gives off a gasoline-like odor, generally does not have a color, and is a liquid. Pentane is commonly used in fuels, building construction materials, explosive materials, food packaging, paint, liquid chromatography, and toys just to…

INTRODUCTION Fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most of the naturally occurring fatty acids contain unbranched chain of an even number of carbon atoms, from 4 to 28. We usually derived fatty acids from triglycerides or phospholipids. Fatty acids are very important sources of fuel because, when they metabolized, they yield large amount of ATP .Fatty acids are regulated by certain transcription factors which control the action of…

middle metal atom. 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…

Dalton an ancient Greek. The mass number is the same number of particles in the nucleus, which is sometimes referred to as Dalton (DA). (Book) Democritus stated that all matter was made up of atoms, which he called atomos. (Early Ideas Prezi) Aristotle seemed to disagree with him. Democritus said that atoms moved through empty space, which Aristotle said did not exist. (Early Ideas Prezi) These experiments were the fundamental building blocks needed to come up with this theory. It began…

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…

Normally, ionic solids are brittle. The bonding of sodium and chlorine is shown below. Metallic Bonding The bonding of metal to metal atoms is called metallic bonding. It occurs between two or more metal cations. In fact, metal atom will lose valence electrons when forming compounds. Every metal atoms share their electrons with the others, therefore producing a mobile electron cloud. Valence electrons are that can participate in a bonding. Crystals are held by…

Question 1 What happen if a person touch liquid nitrogen avoiding the atomic repulsion? It will produce an explosion or nothing will happen? Question 2 It is possible to create an artificial neutron start with the knowledge that humanity have nowadays atoms? (I do not really sure if this question can be considerate part of the course, but at the same time that I watch the podcast, I start to search about neutrons and I found this video in You Tube about the neutron starts, it is origin and it…

Solubility of alcohols in water Small alcohols are completely soluble in water; mixing the two in any proportion generates a single solution. However, solubility decreases as the length of the hydrocarbon chain in the alcohol increases. At four carbon atoms and beyond, the decrease in solubility is noticeable; a two-layered substance may appear in a test tube when the two are mixed. Consider ethanol as a typical small alcohol. In both pure water and pure ethanol the main intermolecular…

Science is intuitive. The tallest hill can be the shortest mountain. It is through our intuition that we come to know that the big ones are mountains and the little ones are hills. In some ways, the same is true for science. Science encompasses everything ranging from chemistry to archaeology, microbiology to astronomy. There are so many different aspects to science that it is hard to boil down to one concrete and concise definition. Science is involved with the study of the natural world. This…
