Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

The Determination of Keq for FeSCN2+ Joy Muthami February 12 2014 Introduction: The purpose of this lab was to calculate the equilibrium constant for the reaction of iron (III) ions with thiocyanate ions. The materials were first acquired then with the groups in the class each team was given a test solution to create and acquire information from then all the information was put together in order to save time. Specifically the group created test solutions #8‚ #9‚ and #10. Once the solutions were

Objectives To study the quantitative relationship between the amount of reactants and products of a reaction ( that is how many moles of A react with a given mol of B). A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium Introduction Stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction. Stoichiometry can be used to calculate the

Introduction: In this lab a total of six titrations are to be performed. Three of them will be done using a known Ca2+ solution‚ (1.000 g CaCO3 /L solution) and three of them will be done using an unknown solution obtained from the stock room. The objective of this lab is to determine the hardness of water‚ using the data collected from each titration performed with the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the

Introduction A system is considered in a state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state

Self determination means the right to determine ones own life. Client self determination in the context of modern day social work relates to the idea that we want our work to be anti oppressive and to empower our clients. It’s a theory that requires that we respect our client’s rights and dignity and we believe that nobody is more qualified to run their lives but them. The Australian Association of Social Workers Code of Ethics (AASW) outlines the role of the social worker and puts in place ethical
