Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

Investigating the water potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then

Specific heat is the property of the material that an object is made of. The greater the material’s specific heat and the mass‚ the more energy must be added to change its temperature. The goals of this lab were to calculate the specific heat of water and compare to the known value of 4.19J/°Cg. Another goal was to calculate the efficiency of the hot pot used for the experiment and to estimate the cost to heat water for a cup of tea and to bath in a bathtub. The thermal energy E= cm Δ T‚ required

Crime and Society Amanda L The diversity of subject matter is the very thing that makes criminal law enforcement such a perplexing question. No other function attempted by organized society covers a wider variety of scientific knowledge and none is more in need of new scientific exploration. In contrast with the occasional flares of public indignation over criminal outbreaks the smoldering light of knowledge illuminates only feebly the field of human relations. The most difficult

to you about my specific fear. Fear‚ the mere sight of the word makes us cringe. It is a feeling we have all dealt with at one time or another. It is a feeling that we first experience when we are small‚ and are conditioned to respond to in many different ways. Some of us live in constant fear; of accidents‚ of bad people doing us harm‚ or of physical ailments. Everybody in the world which we reside has a fear of something‚ including me. The specific fear of mine is the moment when I have to cross

Cebu Institute of Technology Phys 202 /K3 I. Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance
