Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2 B is the magnetic field at the location of the coil. A is the cross sectional area of the coil‚ and Θ is the angle between the field and the area A. There is several different ways to create

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

1. Functions of departments in Thanh Dung Company * BOD: The main function of the board is to manage the business in the best interest‚ primarily of the shareholders. In other words it is their duty to add value to the business which‚ by definition‚ requires the director to ensure that the Thanh Dung Company continues to improve its profitability and the price or value of its shares. They will set up targets‚ policies and strategies to create the premise for the operation of Thanh Dung Company

The Formation of Alum Experiment 4 Introduction In an increasing population the need for land fields are as well increasing daily. Better yet‚ rather than dumping off trash is to instead recycle aluminum cans for a more efficient society. In this lab we will show how aluminum cans react to form alum. Materials and Methods The first step of the lab is to measure the mass of 250 mL beaker‚ once you have done this add .9 to 1.2 grams of aluminum can pieces to the beaker. Take the mass once
