Make a sketch of an electrolysis cell that electroplates copper onto other metal surfaces. Label the anode and the cathode and indicate the reactions that occur at each.
Chapter 5: Gasses Tuesday, January 19, 2016 11:24 PM NOTE: When dealing with gasses, Temperature needs to be in Kelvin! Pressure is created through the force of collision of particles with a surface. Pressure= Force/Area As temp increases so does the pressure PV=nRT o R= ideal gas constant 0.08206 L*atm/mol*K 8.3145 J/mol*K 62.364 L*torr/mol*K Combined Gas Law o P1V1/n1T1= P 2 2n 2 2 Standard pressure is equal to exactly one atmosphere Standard Temperature is 273 K or 0 ̊C Kinetic Molecular Theory Gas is always moving Energy is imparted through collisions of other particles There is a lot of empty space between particles o Average Kinetic Energy of a particle proportional to its temp in Kelvin As temp rises the energy increases KE= 1/2mv 2 Mass units= kilograms (kg) Not all particles move at the same speed. Molecular Velocity The speeds at which the particles travel will follow a Boltzmann distribution o Found with using the average velocity of the particles traveling o KE= 3/2RT Average Kinetic Energy of a gas depends on the mass and average velocity KE=1/2mv = 1/2m= 3/2RT With different masses, in order to have the sam
