In this experiment, identifying the acids, bases, or neutrality of the unknown substance in a specific set are used to find the actual substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver…

While azulene and naphthalene have the same formula of C10H8, their differing arrangement of carbon atoms in rings causes disparities in their molecular orbitals. As shown in the energy difference calculations below Table 1, naphthalene has an energy difference of -10.184 between its HOMO and LUMO orbitals while azulene has one of +6.904. The low energy difference of naphthalene FMOs would suggest that its HOMO and LUMO orbitals have relatively similar distributions of electron density among odd…

Elements are made of a single type of atom, which cannot be broken down into anything smaller. Inside an atom are the subatomic particles protons (positively charged) and neutrons (neutral), and outside are the electrons (negatively charged) that orbit the atom in an electron cloud. When two or more atoms of an element or elements bond together, they form a compound. Depending on the type of elements, there are different kinds of bonds that could form. Ionic bonds form between the atoms of at…

Free radicals are molecules that have at least one unpaired electron. They are typically very reactive, due to their odd number of electrons. These molecules tend to try and gain or lose electrons so their highest energy levels can be filled. They will bond with other compounds in the body, sometimes combining with them, or even taking parts of intact molecules, resulting in even more free radicals (Walling). Free radicals can be formed by natural body processes, such as metabolism. They…

Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

Afra Ankita Class 625 EV3 Test 3 The threshold for white was any intensity above 95%. The threshold for black was any intensity below 6%. This is because the first white surface that was tested for its reflected light intensity turned out to be 95%. The second test for white was 100%, the third was 97%. All these tests were made by using “Port View” on the robot.“Port View” can be found by going to “Utilities” on the robot’s screen. Then going over to the port that the color sensor is connected…

To start off with this experiment, we drew dot structures for each compound and decided whether the compound was polar, nonpolar, or ionic. We found that KCl and CaCl*2H2O were ionic compounds, so we used the electrical conductivity tester to insure us that they indeed conducted electricity. After testing these two compounds, we decided that KCl was the solution labeled “Wolves” and CaCl*2H2O was the solution labeled “Swarm”. We decided this because we knew that the CaCl*2H2O compound was a…

Lab 1 – Ion Exchange Chromatography Danielle Small John Wright 20/01/2016 Introduction: This lab will use ion exchange chromatography – a process in which differently charged ions are separated, by altering the pH of the solution; which shifts the equilibrium of the molecules. During this lab we will separate two compounds from one solute that will be formed by amalgamating a ‘slurry’ – provided by the instructor. Resin or cellulose is used to create a sound support unit in order maintain a…

Purpose: By doing this experiment, students will properly complete a redox titration well also determining the amount of hypochlorite ions present in the commercial bleach given. Introduction: Commercial Bleach and other commercial products like hair colouring agents, contain oxidizing agents. Oxidizing agents are substances that remove electrons from one or more reactants and thereby oxidizes it, whereas reducing agents are substance that give electrons to other reactant. There is some…
