w The Effect of Changing the surface area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area

Examining The Elements of Thought & Right Questions Participating in a changing and increasingly complex society requires citizens to process large amounts of information and to operate effectively in ambiguous and unstructured situations. Such work demands thinking and thoughtful people. (Grant‚ 1988‚ p. 36) The importance of critical thinking is directly linked to the ability to make sound‚ informed decisions. The results of those decisions could have a major impact

Examining Symbolism Our lives have many walls that we must either stand there and look at or decide to walk around the walls of our lives. The foundation of every building has outer walls that construct the perimeter of the building. Dividing every floor of the building there are walls that serve a purpose to compose of obtaining smaller rooms. To have a wall is to surround‚ separate or guard but the walls often do more than this job. In the readings of Bartleby‚ the Scrivener: A Story of

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

EFFECT OF INTEREST RATE ON INVESTMENT DETERMINATION IN NIGERIA (1970-2008) ABSTRACT This study examines the effect of interest rate on investment determination in Nigeria. The study is necessitated by the fact that the behavior of interest rates to a large extent determines investment activities and economic growth of any country. Investment decision is seen as demand for credit in an economy and this study calculated the annual variance of interest rate and its effects on investment determination

The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused
