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

versus floating exchange rates Introduction The exchange rate regime The exchange rate regime is the way a country manages its currency in respect to foreign currencies and the foreign exchange market. Each country has its exchange rate policy which determines the form of a government influence on the currency exchange rate. There are three main type of the exchange rate regime: • a floating exchange rate‚ where the market dictates the movements of the exchange rate‚ • and the fixed

Assignment 4 5. According to the IS-LM model‚ what happens to the interest rate‚ income‚ consumption and invest under the following circumstances. a. The central bank increases money supply. An increase in the money supple shifts the LM curve downward. The equilibrium moves from point A to point B. Income rises from Y1 to Y2 and the interest rate falls from r1 to r2. Therefore this increase in money supply causes a decrease in interest rate‚ an increase in income‚ an increase in consumption and an increase

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
