Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

History 101: Pass the Popcorn‚ Please In the “History 101: Pass the Popcorn‚ Please‚” published in the San Diego Union-Tribune‚ Elaine Minamide‚ a freelance writer and an adjunct instructor at Palomar Community College‚ discusses the disadvantages of using films in the classroom. She points out some common beliefs about using entertainment as a way for educational purposes; the belief that showing films in history class can encourage students to search about history and learn better; the belief

the popcorn. This temperature change of the water is due to the cheeseball having more energy due to its fats and sugars‚ therefore releasing more heat and differing the temperature more than the popcorn with the less fat and sugar. The mass of the food was consistent throughout the experiment ranging from 2.98 - 3.25‚ therefore the mass of food combusted was consistent as well. The strengths of the investigation was the initial temperature of water being the same for the microwave popcorn and the

College students from Yale University were asked to participate in an experiment to test the effects of punishment on learning. They were willing to continue

or vary in some way. By employing both experimental and control groups in an experiment‚ investigators are enabled to rule out the possibility that something other than the experimental manipulation produced the results observed during the experiment. This type of research can be broadly divided into three main types: The Laboratory Experiment‚ The Field Experiment and The Natural Experiment. In a laboratory experiment‚ there is a systematic variation of the independent variables while other irrelevant

v. Reliability The experiment was unreliable. This is because no repeat trials were performed. A number of possible inconsistencies were outlined with regards to accuracy. As no repeat trials were performed‚ the results obtained may have merely been the outliers in the experiment so therefore be unreliable. This is because repeat trials need to be performed until a constant result is obtained in order for the experiment to be considered reliable. Ideally‚ a number of repeat trials should have been

less. Literature Review Many experiments have been conducted to test the strength and absorbency of paper towels. While the steps of the experiment vary from test to test‚ all of experiments are testing the same two factors; how much water can each paper towel brand absorb and how strong are each of the paper towels. Below I have reviewed the process and results from three experiments that are similar to the one I will be using. In the first experiment‚ the tester uses five brands of paper
