experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate of collisions will also

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

Evaluate the impact of government’s influence on the proximate variables in attempting to achieve a desired fertility rate If follows that if the cost of living and the cost of having children limits family size‚ then government policies towards taxation and family welfare are also significant influences on how many children a couple will have. Such government policies generally include family planning programmes‚ financial incentives to control/increase family size‚ and the provision of health

Analysis of High Turnover Rate Introduction High turnover rate of minorities and female employees has become a serious issue in the United States. Even though many ethnic races form this country‚ male Anglo-Saxons dominate the majority of the workforce. It is not uncommon for minority and female employees to leave their company after only working for a few years. Why has this behavior become a trend? In order to stop this trend‚ companies must ask themselves several questions. For example‚ what

Japan is also a Key U.S. Business Partner in importing and exporting goods and services. Through our findings we have developed our insight of the Japanese Yen being very volatile to the dollar. In the graph shown below‚ we can conclude that from 1995 till 1999 the Japanese yen was weaker against Dollar. The process has been repeated between the years 2001-03 and 2006-recent

The paper also discusses the high turnover in the hospitality industry in the context of the lifestyle and attitudes of younger employees who constitute the major portions of the human resource and hospitality industry. The paper finally makes recommendations as to how the attrition can be reduced to a minimum and to increase the rate of attention of the employees in the hospitality industry. 2

L.O CYP 3.1 1.2 The difference between sequence of development and rate of development. Children will usually follow the same pattern of development‚ the ages of which they reach them could vary depending on them as an individual as each child is unique and will develop at their own rate. Goals of development are given on a wide average of when the children may be expected to reach this particular stage. In schools some children stand out from the rest of the class because they have reached

Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This is a well informed

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the
