Question

cannot determine without delta H^o_f for O_2(g) Chlorine will oxidize I^- as shown in this equation: CI_2 + 2I^- rightarrow I_2 + 2CI^- Use reactively trends to predict which can be used to prepare Br_2 from Br^-. F_2 + Br^- CI_2 + Br^- I_2 + Br^- III only I and II only II and III only I, II, and III standard Reduction Potentials, A buried metal tank will not corrode if it is wired to a metal rod that corrodes more easily. Which combination protects the tank from corrosion? Mg rod and Sn tank Fe rod and Zn tank Fe rod and Al tank Cu rod and Zn tank

Explanation / Answer

Question 17:

Answer: (C) II and III only because the bromine is reactive with this reagents.

Question 18:

Answer. (B) Because the difference of Potentials is minimum.
