graph show that there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area because the Agar cubes with a

or increased in number‚ the reaction will increase in rate because faster collisions will take place making more successful collisions. This diagram shows five solutions hydrochloric acid and magnesium ribbon that are reacting. The arrows represent a simplified way to show how many successful collisions occur each second; therefore the more arrows there are‚ the faster the rate of reaction. They show how different factors can affect the rate of reaction against these two reactants (magnesium and

Glossary: 1) Interest rates: An interest rate is the rate at which interest is paid by borrowers to use the money they borrow from a lender. The annualized cost of credit or debt calculated as the percentage ratio of interest to the client. Each bank can determine its own interest rate on loans‚ but in practice local rates are about the same from bank to bank. In general‚ interest rates rise in periods of inflation‚ higher demand for credit‚ narrow money‚ or because of higher reserve requirements

THE IMPACT OF EXCHANGE RATE FLUCTUATION ON MACROECONOMIC PERFORMANCE IN NIGERIA CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY This study is designed to examine the causes of exchange rate fluctuations and their impact on the Nigerian economy since there is scarcely any country that lives in absolute autarky in this globalised world. The economies of all the countries of the world are linked directly or indirectly through asset or/and goods markets. This linkage is made possible through

have different demands in the current industry. The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on how does the carbon chain length of carboxylic acid and alcohol affects the rate constant and equilibrium constant of esterification. Thus‚

analysing the graph‚ you can see that there is a relation between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

The goal of this study is to examine how total healthcare spending and the use of conditional cash transfer programs affect the under-5 mortality rate across different countries. The response variable is the under-5 mortality rate in each country. This is measured by the number of deaths of children under 5 years old per 1‚000 lives births. The numerical explanatory variable is the total health care expenditure by each country. This includes both the public and private health care expenditures in
