In the poem “Dulce et Decorum Est” written by Wilfred Owen, Owen uses painfully graphic imagery to rebuke a claim that it is an honor for one to die for their country. To get his point across, Owen takes full advantage of the shock factor to convince the readers that fighting a war for your country could lead to extremely horrible suffering and death from the effects of chemical warfare. During the first World War (which coincides with the timeframe this poem was written) chemical warfare was being
The Factors Controlling the Rate of the Sodium Thiosulphate and Acid Reaction Planning I am investigating the factors controlling the rate of thiosulphate / acid reaction. The reaction that will be taking place will follow the rate at which sulphur is formed in the reaction of sodium thiosulphate with dilute hydrochloric acid. In the experiment the sulphur will appear as an extremely fine precipitate. This will slowly be followed by a milky appearance in the reaction
Introduction: This experiment involved the synthesis of diphenylmethanal from phenylmagnesium bromide which is a Grignard reagent, and benzaldehyde which is a carbonyl group. The goal of this experiment was to investigate the ability of the Grignard reaction to yield the theoretical predicted product and evaluate its efficiency. The Grignard reaction is an important reaction because of its ability to allow the formation of carbon-carbon bonds. These formations of C-C sigma bonds, then allow for
Chemistry Abstract This experiment was performed to determine the rate constant k, for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation of hydrochloric acid. The rate of hydrochloric acid formation was measured
Name: Joie Vincent R. Dagohoy Date performed: 07-01-13 Student Number: 2009-33281 Date submitted: 07-08-13 Exercise 2 Formulation, Testing of Hypothesis, and Experimental Design I. Objectives: a. to define diffusion and demonstrate this process in gases b. to cite molecular weight and time as two factors affecting the rate of diffusion c. to formulate a hypothesis on the relationship of each of these factors on the rate of diffusion d. to conduct and experiment
since the product/precipitate is produced faster, therefore the rate of reaction will increase. Balanced chemical equation of what will happen: Na2S2O3 + 2HCl = 2NaCl + S + H2O+ SO2 Word Equation: sodium thiosulphate + hydrochloric acid = sodium chloride (salt) + sulphur + water + sulphur dioxide Independent Variables: ❖ Increase in temperature of sodium thiosulfate 1) 40 degrees 2) 50
chemical formula. In this experiment, we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper, chlorine, and water molecules locked in the crystal structure of the solid compound of Copper Chloride Hydrate. First we will gently heat a sample of the compound to drive off the water of hydration. By measuring the mass of the sample before and after heating we can determine
ZnxCly (s) + y/2H2(g) by the information obtained from the lab. When zinc and hydrochloric acid are mixed together, the reaction took place in an evaporating dish that was accompanied by hydrogen gas. Then we measured out the mass of zinc and chlorine in the reaction and calculated the empirical formula of zinc chloride which was ZnCl8. Based on the conservation of mass, we balanced the equation and got Zn(s) + 8 HCl (aq) → ZnCl8 (s) + 4 H2 (g). In the second part of the experiment, we obtained copper
Aim: To investigate the effect of temperature on the reaction rate of hydrochloric acid and magnesium. Introduction: Chemistry happens everywhere, not just in a lab. Matter interacts to form new substances through a process called a chemical reaction. Your body lives and grows because of chemical reactions, whether by taking medicine or even a breath. A chemical reaction is defined as the process that involves rearrangement of the ionic structure of a substance. A reaction rate is how fast or slow
for reacting dilute acids with magnesium would be: If you react Magnesium with dilute Hydrochloric acid then the Magnesium will react with the Chloride ion and Hydrogen gas will be released. Procedure Objective One: heating hydrated chemical substances (Group A) The hydrated chemical substance we chose was Barium chloride First add 0.445g of Barium Chloride to the crucible and place it on the triangular clay, then start heating it smoothly using a Bunsen burner, and then wait observe any changes
