Question

Which of the following are redox reactions? For those that
are, indicate which element is oxidized and which is reduced.
For those that are not, indicate whether they are precipitation
or neutralization reactions.
(a) P4(s) + 10 HClO(aq) + 6 H2O(l)-------->4 H3PO4(aq) + 10 HCl(aq)

(b) Br2(l) + 2 K1s------------>2 KBr(s)
(c) CH3CH2OH(l) + 3 O2(g)------>3 H2O(l) + 2 CO2(g)
(d) ZnCl2(aq) + 2 NaOH(aq)------>Zn(OH)2(s) +2 NaCl(aq)
