This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

Evaluation of a Method to Reduce Over-the-Counter Medication Dosing Error Marion Grady 3/9/2010 What is the purpose of the article? The purpose of the article was to find a simple way of dosing over was a reduction in errors in the home dosing. What are the overall research questions? Research questions include dose determination and dose measurement percentage. The clinical trial randomly assigned color coded or conventional assignments to care givers.

Please refer to the text or simply ask me for help if you need more explanation of the common errors described here. Punctuation Problems When you have a series of items‚ you must use a comma before the ‘and’ or the ‘or.’ When you use ‘however’ within a sentence‚ you must have a comma on either side of the word. Or‚ you could have no commas at all. But‚ you cannot use just one comma unless ‘However’ is the first word in the sentence. Introductory subordinate clauses need a comma to set them off

For Shakespeare to use a woman as a secondary character also for her to have such a predominant and effective voice in the play to a platform unusually prevalent for a women at the time. In The Comedy of Errors we are introduced to Adriana and Luciana‚ these are the only female characters in the play. The women have little influence to what actually happens in the play; however they demonstrate more sensitivity and complexity than all of the males in the

the quantity. The art of estimating these deviations should probably be called uncertainty analysis‚ but for historical reasons is referred to as error analysis. This document contains brief discussions about how errors are reported‚ the kinds of errors that can occur‚ how to estimate random errors‚ and how to carry error estimates into calculated results. We are not‚ and will not be‚ concerned with the “percent error” exercises common in high school‚ where the student is content with calculating

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different
