Investigating Rates of Reaction between Hydrochloric Acid and Magnesium Introduction What is Rate of Reaction? The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. For example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second. In this case how fast Magnesium reacts

Experiment The Rate of a Chemical Reaction: A Clock Reaction Andrea Deoudes February 2, 2010 Introduction: The rates of chemical reactions and the ability to control those rates are crucial aspects of life. Chemical kinetics is the study of the rates at which chemical reactions occur, the factors that affect the speed of reactions, and the mechanisms by which reactions proceed. The reaction rate depends on the reactants, the concentrations of the reactants, the temperature at which the reaction takes place

INTRODUCTION Rationale of the Study Fusarium proliferatum is known as the conidial stage of Giberellafujikuroi, which is an ascomycetous seed-borne fungus that causes bakanae, a disease that influences rice (Nelson, 1994). There are over 100 species of the genus, Fusarium, and they are most common in tropical and subtropical areas. The presence of pathogenic conidia may cause the discoloration in kernels. F. proliferatum is a filamentous fungus or mould found in aerobiologic surveys worldwide.

Learning with Cases INTRODUCTION The case study method of teaching used in management education is quite different from most of the methods of teaching used at the school and undergraduate course levels. Unlike traditional lecture-based teaching where student participation in the classroom is minimal, the case method is an active learning method, which requires participation and involvement from the student in the classroom. For students who have been exposed only to the traditional teaching methods
