TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

Warburg Pinus and emgs: The IPO Decision | Executve Summary With wide geographic and sectorial reach‚ Warburg Pincus had a flat structure and decentralized deal approval process. In the first part of our report‚ we commented on the merits of these features and how they helped the group make investments. Warburg Pincus acquired emgs in 2004 and was considering its IPO. Throughout time‚ Warburg Pinus had added real value to emgs via operational‚ financial and strategic improvements. We believed

translates it to an electrical signal‚ which then gets sent to the central nervous system. The second piece is an interneuron in the integration center‚ which is a processing center that determines the strength of the response of the incoming stimulus. The third piece is a motor‚ or efferent neuron. The motor neuron will take the information received from the interneuron and send it on to its effectors (muscles or glands)‚ which will activate a response. The patellar reflex is classified as a somatic reflex

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

(Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid?

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These
