(COOH)2 = Co + Co2 +H2O. Balance please
Answers
Answer:
This is an oxidation-reduction (redox) reaction:
CIII + e- → CII
(reduction)
CIII - 1 e- → CIV
(oxidation)
(COOH)2 is both an oxidizing and a reducing agent (disproportionation (dismutation)).
This is a gas evolution reaction, CO2 and CO is the formed gas.
