Chemical compound

particles called atoms All atoms of an element are identical Atoms are rearranged to form new substances in chemical reactions, but they are never created or destroyed Atoms of different elements.That model had five main points which included atoms made up all matter, cannot be created nor destroyed, can be told apart by their weights, when combine they will react, and of different elements form compounds in whole number ratios. His experiment started around 1803 and went to 1808. His model…

one needed to find the equilibrium concentration of the compound. In order to do this, Beer’s Law, which relates absorption to concentration, was implemented. The reference solutions were created as a way to formulate a Beer’s Law plot by way of measuring a known concentration of FeSCN2+ and measuring its absorption; varying amounts of each reaction were mixed together in a solution to have multiple points on the plot. When mixing the compounds together, a dilution occurs, where both reactants…

Topic 1: Chemical bonding 1.True or False: An Ion is when an atom gains or loses an electron. 2.What is a Cation? An ion with a (+) charge. 3.True or False: An Anion does not have a (-) charge. 4.What type of bonding transfers electrons? Ionic bonding 5.What are all the types of chemical bonds? Ionic, Covalent, and Metallic bonding. 6.What do you call an element that has different forms . Isotopes 7.Which type of bonding is the “strongest”? Ionic bonding 8.True or False: Ionic bonds are formed…

Lab #4: Physical or Chemical Changes Formal Report Purpose Everything can change from one substance to another, but the creation and the end of some objects never happen. On a beautiful day on the fourth of December in 2015, the class of SNC1D5 started a lab on different kinds of molecules. The objective of this lab was to investigate the chemical and physical changes between different substances. With chemical reactions, reactants or heat, substances can change from one substance to another…

first modern Chemistry textbook. While his textbook did have a few errors it made important advancements such as defining a chemical element as a substance that cannot be reduced in weight by a chemical reaction. Not only did he make these discoveries and observations but he also assisted in creating the metric…

of water, a brown pigment, called “melanoidin” is formed after polymerization and odor and flavor of molecules resulted. In the process, hundreds of different flavor compounds are created. These compounds in turn break down to form yet more new flavor compounds, and so on. Each type of food has a very distinctive set of flavor compounds that are formed during…

of 35.45 amu. It has a melting point of -100.98 degrees Celsius and a boing point of -34.6 degrees Celsius. However, at room temperature it is a gas. Chlorine contains 17 protons and 17 electrons and also contains 18 neutrons. The density of the chemical element Chlorine is 3.214 c/cm3. Like every member of the halogen group, chlorine has a tendency to gain one electron and become a chloride ion. Chlorine…

The chemical Mercury, symbolized as Hg, is an element most prominently found as a solid metal throughout Earth’s surface. It is a naturally occurring element found in Earth’s soil, water and air. To name a few examples of how Mercury is created, there are forest fires and volcanic eruptions whose combustion creates Mercury. In addition, humans also create Mercury through incinerators used in power plants. Mercury is known to be very poisonous to humans and affects many organisms ranging from…

My chemical element is Sulfur. If you were to be looking at a periodic table, its symbol would be S. Sulfur’s atomic number is 16. Sulfur has 16 protons, 16 electrons, and 16 neutrons. Sulfur’s atomic mass is 32.065 and its mass number is 32. Sulfur comes from the Sanskrit word “Sulvere” and also the latin word “Sulphurium”. Sulfur was discovered in Ancient times and has been mentioned in both the Bible and the Torah. Sulfur is commonly found in meteorites, volcanoes, hot springs, and as…
