Unformatted text preview: is the oxidation number of carbon in Zn(C2H3O2)2? Show all work.
Notice that C is associated with the acetate ion (C2H3O2-) in this ionic compound
so you can ignore the Zn2+. Assuming that both carbons have the same
oxidation number (call it x), the following relationship applies.
2x + 3(+1) + 2(-2) = -1
Solving this yields x = 0. Chem 321
3. Name Answer Key Is the following reaction a redox process? If so, what is being oxidized? If not,
explain why. (3)
CaC2 + 2H2O 6 Ca(OH)2 + C2H2 This is not a redox process. No element is changing oxidation number. DATA
Electrode E0 (volts) Ni2+/Ni -0.236...
