Problem

You may want to reference (Pages 138 - 144) Section 4.4 while completing this problem.

Which of the following are redox reactions? 

(a) P4(s) + 10HClO(aq) + 6H2O(l) →  4H3PO4(aq) + 10HCl(aq)

(b) Br2(l) + 2K(s) → 2KBr(s)

(c) CH3CH2OH(l) + 3O2(g) → 3H2O(l) + 2CO2(g)

(d) ZnCl2(aq) + 2NaOH(aq) → Zn(OH)2(s) + 2NaCl(aq)
