Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of reaction by measuring the volume of CO2(g) produced with time. Background: When solid reactants are mixed with liquid reactants only the particles on the surface of the solid will have direct contact‚ or collide‚ to the other liquid reactant particles. When there is more surface area there will be more solid particles exposed to collide

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 increases the

The electoral or voting system in any country or within a state is a very integral part of the country’s progress. It does not only extend to the economic or political independence‚ but it also signifies the society’s struggle in achieving self-sufficiency and freedom. There are different types of election processes such as the plurality election‚ majority election‚ place election and the at-large election. These types differ in the procedures and as such‚ have distinct features that render the strength

There are five types of elections in the United Kingdom: • General elections • Elections to devolved parliaments and assemblies • Elections to the European Parliament • Local elections and mayoral elections Elections are held on Election Day‚ which is conventionally a Thursday. General elections have fixed dates‚ and must be called within five years of the opening of parliament following the last election. Other elections are held on fixed and well as well dates though

This concept applies to cells and reaction rate because cells need to absorb their food‚ water and oxygen through their cell membrane and depending

Deep‚ surface and strategic. Evaluate these approaches to learning Nowadays‚ approaches to learning (deep‚ surface and strategic learning) are increasingly popular in the contemporary world. But in the meantime‚ which approach is the most effective has become a highly debated issue. Some students adopt a surface approach to their studies (Lublin‚ 2006) and others adopt a deep approach (Morgan‚ 1993). Therefore‚ this essay will analyze deep‚ surface and strategic learning‚ and show that these three

especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing position in the water. But how does the surface area of an object affect its buoyancy

‘The Irish electoral system of PR-STV is fundamentally flawed and should be replaced by the Single Member Plurality System (commonly referred to as ‘first past the post’)’ In this essay I will discuss the issues with the Irish electoral system of Proportional Representation by the Single Transferable Vote (PR-STV) and whether or not it is fundamentally flawed and should be replaced by the Single Member Plurality System (first past the post). The first essential feature of the Irish system is it
