An electrochemical cell contains a standard hydrogen electrode and a cathode consisting of a metallic chromium electrode, Cr(s), in contact with a 1.00 M chromium solution, Cr3+(aq). The voltage produced by this cell was measured at 25°C. Which statements describe the results of this measurement, assuming the conditions are ideal? The cell voltage with the appropriate sign equalsI. the oxidation potentialII. the driving force for the transfer of electrons between reactants. III. the standard cell potential. IV. the standard reduction potential for Cr3+/Cr.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

explanation:

sup bro, im dumb, but this is what i found xd

"the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface"
