Which of the following is a redox reaction? More than one answer
may be correct.
HBr(aq) + KOH(aq) → H2O(l) + KBr(aq) SO3(g) + H2O(l) →
H2SO4(aq)
HBr(aq) + Na2S(aq) → NaBr(aq) + H2S(g)
NH4+(aq) + 2 O2(g) → H2O(l) + NO3–(aq) + 2 H+(aq)
2 Na(s) + Cl2(g) → 2 NaCl(s)
None of the above are redox reactions.
c. Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
Is this a redox reaction? (yes or no)
_____________

i. what is the oxidizing agent?
___________________
ii. what is the reducing agent?
___________________
iii. what species is being oxidized?

balance the following redox reaction in basic solution
Ag(s)+CN-(aq)+ O2(g) -->Ag (CN)2- (aq)
cyanide is not participating in the electrochemical reaction but
does associate with the silver ion formed in a second association
reaction. Balance the electrochemistry first and then add in the
cyanide in by adding an associative reaction to the redox
reaction.
Consider the following unbalanced redox reaction occurring in
acidic solution: H2SO3 (aq) + IO3-(aq) → SO42-(aq) + I2 (aq) a)
Balance the reaction. b) Using your table of standard reduction
potentials, calculate ΔG°rxn for this reaction.
1. Which relationship of reaction rates is correct for
the following reaction?

a. -Δ[NO]/Δtime=
-Δ[O2]/Δtime
b. -Δ[NO]/Δtime=
-Δ[NaNO2]/Δtime
c. Δ[NaNO2]/Δtime =
(1/2)(Δ[CO2]/Δtime)
d. Δ[NaNO2]/Δ time=
-(4)(Δ[O2]/Δtime)
e. Δ[O2]/Δtime =
(2)(Δ[CO2]/Δtime)
4. Which statement is NOT true for the reaction
