fiscal policy designers should opt for a flexible exchange rate system. Nations‚ however‚ which do not have such policy makers should opt instead for a fixed exchange rate system. When attempting to stabilize an economy‚ monetary policy is the most efficient weapon that policymakers possess (Weerapana‚ 2003). In other words‚ it is much simpler to enact monetary policy than fiscal (Weerapana‚ 2003). Some nations benefit from a fixed exchange rate system‚ however. Nations such as Brazil‚ Kenya and Turkey

Chemical reactions are the basis of life on earth. As human beings‚ we are little more than the naturally abundant elements of which we are composed and the reactions between the compounds that they form. After all‚ how could life exist without water? Oxygen transport in a body the size of the human body would be impossible without the aid of a complex like hemoglobin. Besides being the basis of many of life’s intangibles‚ chemistry also plays an active role in our daily lives. Take for instance

THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy D. F. Nachman 6/23/2010 Abstract: An ice calorimeter was used to study the reaction of magnesium metal and 1.00M sulfuric acid solution: Mg(s) + H2SO4(aq) →MgSO4(aq) + H2(g). We found the experimental molar enthalpy of reaction to be ΔH = –355 ± 17 kJ/mol at 0°C‚ 24% lower than the textbook value of ΔH° = –466.9 kJ/mol‚ reported at 25°C. Introduction Whether a chemical reaction occurs spontaneously or is driven by an outside force

There are many different ingredients in a kitchen that causes a chemical reaction with baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct
