Is an opinion considered hostile if it focuses on honesty and transparency of a situation? “Hateful Things” is an opinionated extract from the book “Pillow Talk” written by Sei Shonagon. Pillow Talk is a collection of the lists‚ desires‚ poetry and judgmental conversations by Shonagon. Sei

stories‚ news articles‚ and especially essays begin with good hooks because a writer is often judged within the first few sentences. Just as the news tries to stimulate our fears by announcing a “danger in our water supply‚” a writer must try to bring the reader from his or her world into the world of the essay. This is done with a few choice words at the beginning of the essay: the infamous hook. It is not easy to think of how to make someone want to read an essay about a novel. It’s not even easy to

examine a number of different chemical reactions and determine if they are exothermic or endothermic. Apparatus: • Test tubes {Around 10-12 in number} • Test-tube rack • Spatula • Digital thermometer { ± 0.1° C} • Digital balance {± 0.01 g} • Measuring cylinder {± 0.5cm³} • Different chemicals Introduction/Theory: Exothermic reactions are those reactions that release energy in the form of heat. Endothermic reactions need to absorb energy in the form of heat

How reaction rate varies with sodium thiosulphate concentration Background information Sodium thiosulphate and hydrochloric acid are both colourless liquids‚ when the two reactants are reacted together they produce sulphur. The sulphur that is produced from the reaction changes the solution to yellow and cloudy‚ this is a precipitation reaction‚ where a two solutions react and a solid forms in the solution‚ the solid is said to precipitate out. Some reactions will occur quickly such as fireworks

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Curtis M. Franklin Thursday‚ February 14‚ 2013 ABSTRACT An ice calorimetric measurement was used to determine that a reaction involving solid magnesium metal and 1.00M sulfuric acid produces an experimental a value of ∆H = -226 ± 28 kJ/mol at 0°C. This is about 48.4% lower than the expected value reported at 25°C. Introduction Many chemical reactions exhibit themselves by exchanging heat energy‚ either be absorbing

the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development

Computerized Data Acquisition of a Second Order Reaction Abstract Introduction The rates at which reactions occur depend on the composition and the temperature of the reaction mixture. Usually the rate of reaction is found to be proportional to the concentrations of the reactants raised to a power.1 There are many reactions that have a rate law in the form of: (1) v = k[A]a[B]b According to reference1 the power to which the concentration of a species (product or reactant) is raised

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore

For known amounts of reactants‚ theoretical amounts of product can be calculated in a chemical process. These calculated products are determined using the limiting reagent‚ (the substance that runs out first which stops the reaction) and are called the theoretical yield. The theoretical yield is the amount of product that should be acquired during the experiment if all aspects go perfectly. However‚ due to experimental errors‚ very few labs do so. These results are called actual yield. The percent
