    The genetic code A DNA (deoxyribonucleic acid) is composed of 4 different bases; adenine (A)‚ guanine (G)‚ cytosine (C) and thymine (T). Applying these 4 bases it may contain thousands of sequences within a single strand. Each of these bases makes a specific pairing with a corresponding base whereby the double helix structure is synthesised. This interaction is called base-paring and the complementary base pairs are; T pairs only with A and C only with G. Through this simple coding language‚ the

    Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate

    Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction rate with
