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

cut attrition and the possible new moves and plans to have sustained rate of employees’ retention. 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

Understand the Expected Pattern of Development for Children and Young People From Birth to 19 Years Explain the Difference Between Sequence of Development and Rate of Development and Why The Difference is Important. All children develop at different rates‚ information and sources are only guidelines. These help to monitor what children can and can’t do at certain stages in their lives. It also helps to plan effectively to ensure the child gets the attention they need‚ in the areas in which they find challenging

BPO’s not only recruit fresher from their own centers but they have also approached various consultancies to do them the favor on certain commission basis. The purpose of this research is focused on to find out why the employees are leaving the organization and all the possible reasons why the companies are not able to retain their employees. Review of Literature: High employee turnover rate is problem and because of this many industries have been suffering from losses in term of money and trained

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using

would burn faster. How to test the variable is to burn a scented and unscented candle at the same time and see witch candle burned the quickest. There wasn’t any flaws in this experiment. When changing this experiment use different brands‚ scents or waxes and see which one would burns faster. The results were the unscented candle burned faster but they both burned at the same speed rate so it doesn’t really matter too much. Other brands could change the effect of the burn rate than other brands that

Did any of the environmental factors (heat‚ light‚ or wind) increase the transpiration rate more than the others? Why? The transportation was increased mostly by the fan: 6.4 As it increased the respiration by transporting water away from plant. 4. Which species of plants that you tested had the highest transpiration rates? Why do you think

Despite the sharp decrease in the dropout rate in rural America between the years 1975 and 1993 which essentially closed the gap between the urban and rural dropout rates‚ over 10 percent of rural students still do not finish high school and have difficulty finding gainful employment (e.g.‚ Paasch & Swaim‚ 1995). Graduation is an extremely important milestone in the life of an individual as they prepare for adult life (Paasch & Swaim‚ 1995). For instance‚ high school graduates have a greater chance

shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will
