Question 2 of 10 Map A General Chemistry University Science Books 4th Edition presented by Sapling Learning Donald McQuarrie. Peter A. Rock Ethan Gallogly Complete and balance the equation for this reaction in acidic solution. 2 Zn ZnS NO S NO Tip: If you need to clear your work and reset the equation, click the button that looks like two red arrows. Which element got... Which species was the... reduced? oxidized? oxidizing agent? reducing agent? O Zns O ZnS NO3 NO3 Zn Zn O Zn Zn Previous Give Up & View Solution Check Answer Next Exit YB Hint The half-reactions are 2+ No, No Balance each half-reaction for oxygen atoms, hydrogen atoms, and electrons.

Explanation / Answer

3(ZnS --> Zn2+ + S(s) + 2e-) .................. oxidation
2(4H+ + NO3^- + 3e- --> NO + 2H2O) ..... reduction
------------------- --------------------- ------------------------ ----------------
3ZnS + 8H+ + 2NO3^- --> 3Zn2+ + 3S(s) + 2NO(g) + 4H2O(l)

"Molecular" equation:
3ZnS(s) + 8HNO3(aq) --> 3Zn(NO3)2(aq) + 3S(s) + 2NO(g) + 4H2O(l)

Sulfur is oxidized
Nitrogen is reduced
ZnS is the reducing agent ....... contains the element oxidized
NO3^- is the oxidizing agent .... contains the element reduced
