Scuba tanks are given a max working pressure (mwp) rating that represents the highest pressure the tank can safely hold at a given temperature. In the U.S. the MWP for a tank is 207.0 bar at 20 degrees C. If the tank is filled at 200.0 bar at 20 degrees C, what is the maximum pressure the tank achieves if left in the sun on a boat, if the tank temperature reaches 35.0 degrees C?
In high spin complexes, the crystal field splitting energy is small and in low spin complexes, electrons are concentrated in the lower energy orbitals.
A solution containing Pt4+ is electrolyzed with a current of 5.00 A. How long will it take to plate out 77% of the platinum in 0.50 L of a 0.010 M solution of Pt4+?
