ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. qwater = m × c × ΔT m = mass of water = density x volume = 1 x 26 = 26 grams ΔT = T(mix) - T(water) = 38.9 - 25.3 = 13.6 q(water) = 26 x 13.6 x 4.18 q(water) = 1478 Joules SPECIFIC HEAT: qmetal = -205 J = 15.363 g X c X (27.2 - 100.3 C) c = 0.183 J/gC PART2. Using the formula qmetal = m × c × ΔT‚ calculate the specific heat of the metal. Use the data from

Specific Learning disorder refers to academic performance that is substantially below what would be expected given the person’s age‚ IQ score‚ and education. In the article “Psychoactive Medication and Learning Disabilities”‚ it focuses on the academicals and social behavioral effects of Ritalin and Dexedrine‚ which are psychoactive medications. It is a case study on David‚ a seven years old boy who showed characteristics of ADHD and learning disabilities. His IQ score was 62 according to the Stanford-Binet

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

1.Specific Features of Financial Services Marketing It has been suggested that there are two characteristics‚ which are specific for financial services marketing. The first one would be fiduciary responsibility and the second one is the two-way information flows. 1.1Fiduciary Responsibility Fiduciary responsibility is one of the most important features within the financial sector. It has been described through Arthur Meidan as "the responsibility of any financial services organisation to guard

It prevents contamination from unknown cultures. 3. Does your lab report contain any messages when your inoculation was not complete? What change in the traffic signals indicates an unsuccessful inoculation? Answer: The lab report does not contain any messages about inoculation. There’s only a reference if auto-inoculation was used. The traffic signal light will turn red if the inoculation was unsuccessful. 4. Does you lab report contain any messages when you don’t follow aseptic procedures

Abstract Through three different experiments we were to find the quality of NaCl as a deicer. These experiments included testing the freezing point depression of NaCl in solution at two different concentrations‚ testing for the H of an aqueous NaCl solution‚ and combining NaCl with MgCl2 in an aqueous solution to test for freezing point depression. Through these various experiments we found NaCl to be the best deicer for our region due to its proficient freezing point depression and its cost

In the short story‚ “August Heat‚” W. F. Harvey uses imagery‚ point of view‚ and structure to build intensity‚ and to show how humans cannot control nature. The first person point of view shows how James’s attitude changes over the course of the story. At the beginning‚ James states‚ “I am forty years old‚ in perfect health‚ never having known a day’s illness.” Later in the story‚ James had a‚ “sudden impulse‚” to enter the monumental maker yard.

Stoichiometry lab By: James Stewart Purpose: To calculate mole ratios Introduction: There are two types of chemical analysis; qualitative analysis which is the identification of a substance present in a material‚ and qualitative analysis which measures the amount of the substance. In this lab‚ you will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation

Latent Heat Thermal Storage Using Phase Change Materials (PCM) Aniruthan .M.E ABSTRACT Department of Mechanical Engineering‚ Anand Institute of Higher Technology‚ Chennai. Various methods are employed in production of energy throughout the globe. Some prove as perennial resource‚ however many of them undergoes many loses in the intermediate conversion process from initial stage to the final stage of power production. Also supply and demand don’t quite meet their ends often. To reduce this mismatch
