Biology 104 Reaction Times Objectives: 1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied‚ as its practical implications may be of great consequence‚ e.g. a slower than normal reaction time while driving can have grave results. Many factors have been shown to affect reaction times‚ including age‚ gender‚ physical fitness‚ fatigue‚ distraction

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Coupled Reactions ABSTRACT A way to drive a non-spontaneous reaction forward is by coupling it with another reaction that is highly spontaneous‚ resulting to a spontaneous overall reaction. In this study‚ since the extraction of C(s) from CO2(s) is a non-spontaneous process‚ it was coupled with the oxide formation reaction of Mg‚ a reaction with high spontaneity‚ so that the process of the extraction of C(s) would proceed. The reactions and products which were a mix of black and white

experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get

unable to read or write’ and it is one of the main causes of poverty in any society‚ and Pakistan unfortunately. According to the 1998 census the definition of literacy is ‘one who can read a newspaper and write a simple letter‚ in any language’. Based on this definition Pakistan has a literacy rate of 55% *. Illiteracy contributes to poverty in numerous ways‚ both indirect and direct. The first link between illiteracy and poverty tends to be when the poor man is unable to afford a high quality

Poor in the World The word poor‚ or poverty‚ is eminent but the cause may not be much known. According to the Census‚ almost 50 million Americans live in poverty today and is estimated 1.2 billion people live on less than $1.25 today. Why is this number so high? Why is there poverty in the world at all? The central reason for poor in the world is greed. Most historians would argue that the selfish desire for something is the lack of resources. The United States has more than enough resources necessary

Introduction: This study is about the economic‚ political and socio- cultural conditions of the Urban Poor. Urban poor has become an interesting topic now days since it is very relevant to modern society. Poverty tends to be the greatest ill that plagues the Filipino as a society. The poor ranges from poor‚ very poor‚ and to the very‚ very poor. The topic URBAN POOR was selected from a group of topics given and then given emphasis by the author according to the relevance of this specific group
