Bottled propane is used in areas away from natural gas pipelines for cooking and heating, and is also the source of heat in most gas barbecue grills. Propane burns in oxygen according to the following balanced chemical equation.
C3H8(g) + 5 O2(g) 3 CO2(g) + 4 H2O(g)
Calculate the mass in grams of water vapor produced if 3.09 mol of propane is burned.
Using the equation E0cell = E0cathode - E0anode, and the reference value of E0 for Cu(II)/Cu(s) for the role that copper plays in this overall cell reaction, determine the value of the standard potential for the half-reaction Zn2+(aq) + 2e- -> Zn(..
