An electrochemical cell is set up with 1 M Pb(NO3)2 on one side, and 1 M AgNO3 on the other. a. Which metal will be oxidized? Which will be reduced? Write out balanced half-reactions for these reactions. b. Write out the balanced overall reaction for this electrochemical cell. c. How many moles of electrons will fl ow from the anode to the cathode? d. Calculate the voltage for this electrochemical cell.
What is gas A gas can be made of atoms or molecules or mixtures. Gases have low density, low viscosity, expand and contract with changes in temperature and pressure, distributes uniformly throughout a container. Pressure = force/area 1 atm = 760 mmhg = 760 torr Pascal (Pa) 1 N/m^2 (recommended IUPAC unit) 1 atm = 101325 Pa 1 bar = 100,000 Pa Pounds per square inch (psi), air pressure at sea level is (14.7psi) Boyle’s Law Pressure is inversely proportional to volume at constant temperature. P*V=k(constant) P1*V1=P2*V2 Charles Law Volume directly proportional to temperature at constant pressure. V/T= k (constant) V1/T1=V2/T2 Avogadro's Law Volume of gas is directly proportio
