For a glimpse at how the heart is working, a doctor will measure heart rate during the physical exam. Your heart rate is the number of times your heart beats in one minute. With each heartbeat, a pressure wave (pulse) passes along an artery as its walls bulge and then relax to accommodate the surge of blood. To feel this pulse, you can place your fingers on key blood vessels, like the radial artery on your wrist (Figures 1 and 2) or the carotid artery on your neck where your jaw and neck meet (Figures 3 and 4), and count. What equipment do you need to record this vital sign?

The formula is (nh4)2co3

Not a  mixture of two common elements that can be separated by physical means.

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
