necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity‚ calorimetry will be used to determine the specific heat of an unknown metal. This will be done by using a styrofoam cup calorimeter containing water. A calorimeter is insulated so as to minimize any loss of energy to the surroundings. Therefore

Instead‚ by increasing the concentration of the cathode‚ the voltage of the galvanic cell will decrease due to the equilibrium shift to the left. The highest concentration (1.5 mol dm-3 ) was the lowest out of the 3 trials at 1.68 volts‚ thus proving that the higher concentration the lower the voltage. When the concentration of the product decreases‚ it will drive the equilibrium to the right to minimize the impact. Although‚ the lowest calculation (0.5 mol dm-3) is not necessarily the highest out

Chemical equilibrium is a state of balance within a system of chemical reactions. Equilibrium in chemistry is achieved when substances are produced and broken down at the same rate and thus‚ the number of molecules of each substances becomes constant. Thermodynamics is a branch of physical science that involves the relationship between heat and other forms of energy (Energy‚ Enthalpy‚ and the First Law of Thermodynamics). There is a more specific area of thermodynamics that explicitly pertains to

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

(a) Define the term equilibrium potential and use the Nernst equation (see Appendix) to show how the equilibrium potentials for both sodium and potassium are calculated. Equilibrium potential is the potential of the membrane when there is no net flow of ions from one gradient to the other gradient. The ions are equal and are opposite of each other but not moving from one side to the other. Sodium: Ena=2.303((8.31 J m-1 K-1)(310K))/((1(= 9.65 x 104 c m-1))(log(150/15))= 61.54 mV Ek=2.303((8
