Write the cell notation for an electrochemical cell consisting of an anode where Cr2^+(aq) is oxidized to Cr3^+(aq) at a platinu
m electrode and a cathode where Co2^+(aq) is reduced to Co(s) . Assume all aqueous solutions have a concentration of 1 mol/L and gases have a pressure of 1 bar.
They use fans and air conditioning in the summer because its hot, which means they use energy and in the winter, there is no need because its cold so less energy.
