Alright boys need some chem help again.
The question is...
Quote:
Compose the balanced reaction equation for the following reaction occuring in basic aqueous medium.
Reduce all coefficients to the lowest possible integers.
Include H2O(l) and OH−(aq) appropriately to complete the equation.
Au(s) + CN−(aq) + O2(g) → Au(CN)4−(aq)
|
I got Au(s) + 4CN^-(aq) + O2(g) + 2H2O(l) -> Au(CN)4^-(aq) + 4OH^-(aq) but that is apparently wrong.

Fe(CN)64−(aq) + Ce4+(aq) → Ce(OH)3(s) + Fe(OH)3(s) + CO32−(aq) + NO3−(aq)

I got Fe(CN)6^4-(aq) + 61Ce^4+(aq) + 258OH^- -> 61Ce(OH)3(s) + Fe(OH)3(s) + 6CO3^2-(aq) + 6NO3^-(aq) + 36H2O(l) but again it is apparently wrong.
