Meeting (The Three Graces) is an oil on canvas painting created by Manierre Dawson in 1912. Cubistic in style, the subjects of his painting are three women from Greek mythology commonly known as the three graces. The women were daughters of Zeus who represented traits such as youthfulness, elegance, and beauty. There have been many artworks depicting the three graces, but Manierre Dawson’s stands out from the rest. Dawson’s painting is different from traditional portrayals of the graces because of

Reflection of: “Mark Twain and His Times” The article “Mark Twain and His Times,” by Stephen Railton tells of a time when Mark Twain was the American idol. During the period between 1865 through 1910, Railton declares was “Twain’s time” (Railton, 2010). During this time Mark Twain was in the midst of his lecture tours and live performances, his newspaper articles were being read by people all around the globe, and his fiction books became instant pieces of American literature. His storytelling

Lab report: How does the surface area affect the rate of reaction ? Introduction The rate of a chemical reaction (or reaction rate) is a calculation of the total time needed for a reaction to take place, or how quickly the reactants are transferred into products in a chemical process. This rate can be measured in two methods. The first one is to measure the rate at which the reactants are used up per unit of time, while the second method is to measure the rate at which the products are formed

Aim The aim of this investigation was to experimentally determine the order and rate law expression of the reaction between sodium iodide and iron (III) nitrate 9-hydrate. Introduction The most interesting topic in grade twelve chemistry was the unit on kinetics, therefore after brainstorming a mind map on the stimulus that I chose, I was interested in creating an experiment to determine the order and rate law expression between two reactions myself. The original idea for this project came from

Introduction In the following lab experiment, reactions will be induced in order to experimentally determine both the rate laws and the reaction orders of hydrochloric acid and sodium thiosulfate in the synthesis of the two solutions. A rate law is an equation which can tell you how fast a reaction will take place, dependent on the concentrations of each solution involved. A reaction order, usually described as either zeroth, first, or second order, gives the magnitude of variance when the concentration

In the not so short story “the cold equations” the author presents a hard decision to kill one or many the killing of one to save many is decided. Tom godwin wrote a story about an EDS pilot who find a stowaway-- an 18 year old girl named Marilyn. Marilyn snuck on the little ship halling fever medicine for 6 men that were sent to the planet Woden. The pilot gets to know Marilyn who snuck on the ship to go see her brother who was on the other side of Woden. The rule was any sort of stowaway was to

All the graphs have data points which show the averages of the site between the two trials. There is a line of best fit which has a slope of r², which is the correlation value between canopy cover and the variable tested. Figure 1 shows the average macroinvertebrate rating between Trial 1 and Trial 2. The correlation value (r²) of 0.07 shows an extremely weak, negative relationship between canopy cover and macroinvertebrates. The site with 25% canopy cover had the highest average macroinvertebrate

The unit A.2 test is my best assignment because I find question involving linear functions the easiest to solve. When I learned the four ways to solve linear functions, I learned that if I’m unsure of an answer I can just use a different method to check if I have the same answer. One way to solve the y=mx+b formula when given only two points is to start by plotting the points; then draw a straight line from one of the points to the other. Then count up or down on the Y axis and count right or left

solutions are going to be complex, which methods can be used to solve quadratic equations? Explain your reasoning. When the answers to a quadratic problem are complicated, the quadratic formula or completing the square can be used to solve it. This is because these approaches are designed to produce complicated solutions when the exponent is negative. The quadratic formula is a generic solution for any quadratic equation that provides the two solutions in terms of the problem's coefficients. Completing

My observation took place at The lost dog cafe and my focus was mainly on the host welcoming customers. I started my observation at 6 pm and it took me two hours to complete my assessment. I was sitting at an high top chair right at the front of the restaurant which limited my eyesight to the back part of the restaurant. I decided to sit up front since I assumed the host would be standing at the front of the restaurant but soon I found out that she occasionally went to the back part on the restaurant

0.1M 0.05M 0.025M 0.0125M 0.00625M Use equation C1V1 = C2V2 to calculate the amount of water needed to dilute the solution. 10ml of 0.1M KI + 10ml of deionized water = 20ml of 0.05M KI Measuring the time for the colour change to occur Using a pipette, add 1ml of H2O2, HCl, starch solution

The Relationship between Molecular Weight and the Rate of Diffusion of Substance Anthony Earl D. Cristobal Group 1 Sec. U-7L 16 October 2014 Abstract The relationship between the molecular weight and the diffusion of the substance was determined using two laboratory experiments. In the first experiment, a horizontally placed glass tube was set. Two cotton balls were soaked in hydrochloric acid (HCl) and ammonium hydroxide (NH3). At the same time, the cotton balls were inserted

affects the time the mixed chemicals stay clear before turning blue. The reactions that form the basis for the iodine clock reaction are shown below. Equation 1: H2O2 + 3 I- + 2 H+ → I3- + 2 H2O • H2O2 = Hydrogen peroxide • I- = Iodide ion (from potassium iodide) • H+ = A proton, from hydrochloric acid (HCL) • I3- = Triiodide • H2O = Water Equation

clock reaction are shown below. Equation 1: H2O2 + 3 I- + 2 H+ → I3- + 2 H2O • H2O2 = Hydrogen peroxide • I- = Iodide ion (from potassium iodide) • H+ = A proton, from hydrochloric acid (HCL) • I3- = Triiodide • H2O = Water Equation 1 shows that hydrogen peroxide reacts with iodide ions in acid solution

1. For the demo experiment, the balanced chemical equation is as follows: (NH4)2Cr2O7(s)=Cr2O3(s)+N2(g)+4H2O(g). After the lightning of Ammonium dichromate, Chromium (III) oxide was formed while the Nitrogen and Water escaped into the atmosphere in a gaseous phase. Ammonium dichromate((NH4)2Cr2O7) gave rise to Chromium (III) oxide (Cr2O3), Nitrogen Gas(N2) and water (H2O) In terms of microscopic level, the ratio between reactants and products is as follows. One mole of Ammonium dichromate will give

differentiation formulas since integration is for the reverse of finding the function. A separable differential equation is any differential equation that we can write in the following form, N(y)dy/dx = M(x) Note that in order for a differential equation to be separable all the y's in the differential equation must be multiplied by the derivative and all the x's in the differential equation must be on

were carbon dioxide, water, and sodium acetate. Because this reaction will be based on its speed according to the difference in temperature, the higher the temperature the faster the reaction will occur creating a direct relationship. The balanced equation is as follows: NaHCO3 (aq)+ CH3COOH (aq) →

understand better what affects the rate of reaction and how changing concentration levels will help increase the rate of reaction. Magnesium Metal (ribbon) reacts with hydrochloric acid to form Magnesium Chloride salt, and releases hydrogen gas. The equation is stated

to find out the respective enthalpies of the reactions. These two values completed the Table of Thermochemical Equations given and with respect to Hess’s Law, the heat of formation of solid NaCl was computed by adding the enthalpies in the table. Two Styrofoam cups and a thermometer through its lid served as the calorimeter where the reactions took place. Using the heat transfer equation, the enthalpy of the first reaction was computed to be -1.080 kJ/mol. On the other hand, the enthalpy of the second
