Balanceamento por oxirredução (me ajudem, por favor!!)

Post by machadoge »

Balancear as seguintes equações químicas por óxido-redução:
a) Cr2O72-+H2O2+H+ = Cr3++O2+H2O

b) CO2+H2S = C6H12O6+H2O+S

Please use english

Cr2O7 2- + 14 H+ + 6 e- => 2 Cr 3+ + 7 H2O Reduction

H2O2 => 2 H+ + 2 e- + O2 Oxidation


6 CO2 + 6 H2S = C6H12O6 + 6 H2O + 6 S
