Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration

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

Exchange rate development in Ethiopia Monetary Development The legal tender currency of Ethiopia was issued on 23 July 1945 by defining the monetary unit as the Ethiopia dollar (E$) with a value of 5.52 grains (equivalent to 0.355745 grams) of fine gold. The linkage with fine gold was in accord with the monetary system established by the Bretton Woods Agreement of 1944. For the five years following the proclamation of the national currency (1945–1950)‚ money supply of the country was determined

English Keanu Johnson Period 8 September 18‚ 2012 Teenage Birth Rate Rises Do you know where your tax dollars are being spent? Every year the government is spending tens of millions tax dollars on programs that hurt our children‚ mainly abortions. Abortions rates have risen over the years because teen sex rates have also climbed and the condom use rates has plummeted. Therefore‚ the most important issue facing our nation’s young people today is the use of abortion as a means of contraception

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation
