Chemistry Report on Explosives What is meant byoxidation and show how oxidation reactions are used to cause explosions. Oxidation is the term used for the combinationof a substance with oxygen, or in general any reaction where an atom ormolecule loses electrons. This can be shown as: C(s) + O2 (g)CO (g) S=solid, g=gas Gunpowderor black powder is the oldest explosive we know. It is made […]
Abstract My research question, as the topic states, is ‘How would the concentration of sulfuric acid affect the rate of hydrogen gas produced when it reacts with iron?’ The reason that I want to do this experiment is to prove whether the collision theory in Chapter6.2 of the Chemistry textbook1 is true about the concentration will affect the rate of a reaction. And I also […]
Introduction: Equilibrium is defined as the point at which the forward and reverse rates of a reaction are equal (1). A system in dynamic equilibrium is a specific example of a system in a steady state. In this steady state the rate of inputs and outputs in the system is equal, so the makeup of the system is unchanged over time (3). Le Chatelier’s principle […]
Introduction To describe and explain the chemistry of drug metabolism a basic foundation of knowledge is needed to understand the concepts. Metabolism is one of the methods for analysing the effect of drugs or xenobiotics on the body. It is basically a process of converting lipophilic drugs into more hydrophilic drugs to decrease pharmacological effect and increase subsequent hepatic or renal elimination. So it is […]
Rates of Chemical Reactions- LO3 Questions 1.1 Two Grand-Pa tablets would have the same effect as one Grand-Pa powder this is because Grand-Pa Headache Tablets each contain, Aspirin: 226,8mg, Paracetamol: 162,0mg and Caffeine: 32,4mg where as Grand-Pa Headache Powders each contain Aspirin: 453,6mg, Paracetamol: 324,0 mg and Caffeine: 64,8 mg thus to obtain the same dosage of ingredients, twice the dosage, thus one would have […]
First laser ablation technique was invented in 1960. The history of laser ablation studies begins with the birth of the laser itself. Laser ablation is a technique of removing of material from superficial solid with the help of laser beam. The number of studies grows simultaneously in seventies and they got a great success but it was explored in the year 1985 with many applications […]
Introduction Chemical compounds can generally be classified into two broad groups: molecular compounds and ionic compounds. Molecular compounds involve atoms joined by covalent bonds and can be represented by a variety of formulas. Ionic compounds are composed of ions joined by ionic bonding, and their formulas are generally writtenusing oxidation states. Molecular Compounds Molecular compounds are composed of atoms that are held together by covalent […]
Investigateurinary excretion of paracetamol in man. Paracetamol, known as acetaminophen in the USA, is one of the most commonly used analgesic and antipyretic drugs available over-the-counter. Its common name derives from the full chemical name: para-acetyl-amino-phenol, with the chemical formula C8H9NO2 and amolecular weight of 151.17. Paracetamol does not have anysignificant anti-inflammatory action and therefore cannot be accuratelydescribed as a non-steroidal anti-inflammatory drug (NSAID), as […]
Advances In Textile Dyeing And Textile Wastewater Treatment Using Advanced Oxidation And Membrane Filtration Technologies: A Review Introduction The textile industry is a diverse sector in terms of production of raw materials, operating processes, product development, and equipment. The industry is well-characterized for consuming large amounts of water, energy, and discharging high volumes of waste in to public sewage treatment plants (STP). The main sources […]
In this experiment the constituents of cigarette smoke in undisclosed brands A and B were analysed using Fourier infrared spectroscopy (FTIR). The smoke from the cigarettes of both brands were tested comparing both the levels of carbon monoxide and methane between both brands and the difference in concentration of these constituents in both the filtered and unfiltered of each of the cigarette brands. The results […]
