    many theories as to why and how we know. These theories consist of mainly the Big Bang Theory and how it had created the first and lightest elements in our universe, or Red giants(Dying stars) because as the dying star’s core begins to run out of hydrogen it begins to die and create carbon atoms as a result of it’s death, another piece of evidence we have on this topic is supernova’s because star releases a very large amount…

    The human body is mainly made up of four elemental components: oxygen (65%), Carbon (18%), Hydrogen (10%), and Nitrogen (3%). It is also composed of about 28 other elements including, Potassium, Sodium, and Calcium. Each plays a major role on the daily functions of the human body. Oxygen accounts for roughly about two-thirds of the mass of the human body and is use in cell respiration. Carbon is part of the molecular structure in certain fats, proteins, and carbohydrates; which are essential…

    Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

    occurs when an element gains electrons. Oxidation and Reduction are processes that always work together, hence the term oxidation-reduction reaction or redox reaction. Oxidation is also the gain of oxygen and loss of hydrogen while reduction is the loss of oxygen and gain of hydrogen. Redox reactions occur in everyday life, it is a highly significant form of chemical reaction. Examples of real life redox reactions include: combustion, metabolism of food, biological processes as well as the…

    Experiment 1: Alkanes & alkenes: Combustion and action of sulphuric acid. Objective: To make careful observations and compare the difference(s) between alkanes and alkenes. Introduction: Hydrocarbons are composed exclusively of oxygen and hydrogen. There are three types of homogeneous hydrocarbons (whose members differ by one CH2 unit): alkanes, alkenes and alkynes. The difference between these three groups is in the bond types between the carbons. Alkanes form only single bonds, alkenes…

    Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

    Basicity of Pyridine vs Pyrrole The lower the pKb value of a compound, the stronger a base it is. Since pyridine has a lower pKb value, it is a stronger base than pyrrole. In this example, we cannot use either the steric factor or inductive factor to explain their basicity. Instead, we have to look at the hybridization state of the respective nitrogen atoms. The nitrogen atoms in pyrrole and pyridine are sp2 hybridized because they satisfy the following two conditions: 1) the atom has at least…
