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

LAB WRITE- UP NAME: MANOUCHEKA FIDEL DATE: 9/19/14 TITLE: BACK AND FOURTH MOTION PURPOSE (Introduction): To qualitatively analyze the motion of objects that move back and forth. Then analyze and interpret back and forth motion in kinematics graphs. Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so

(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

Solving Part A: Center of Mass in One Direction 1. Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass is uniform about the axis of symmetry. Therefore‚ the horizontal center of mass will be at the exact

Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting
