Rotation of bar oa is controlled by the lead screw which imparts a horizontal velocity v = 36 mm/s to collar c and causes pin p to travel along the smooth slot. the velocity of collar c is decreasing at a rate of 5 mm/s2 at the instant in question. determine the values of r¨ and θ¨, where r = op¯, if h = 240 mm and x = 190 mm

The formula is (nh4)2co3

Contained in chromosomes which are located in the nucleus of the cell.

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.
