Question

This is the original equation: 2NO_3^- + 3H_2 --> 2NO + 2H_2O + 2OH^-

Is this the oxidation reaction: 3H_2 + 3H_2O + 6OH^- --> 9H_2O + 6e^-

If so, can you reduce it to the lowest coefficients?

Is this the reduction reaction: 2NO_3^- + 8H_2O + 6e- --> 2NO + 4H_2O + 8OH^-

If so, can you reduce it to the lowest coefficients?

 

This is another equation: SO_3^2-+2Cu(OH)_2 --> SO_4^2-+2CuOH+H_2O

I need a balanced oxidation reaction and reduction reaction, please.

 

This is another equation: SO_3^2-+2Cu(OH)_2 --> SO_4^2-+2CuOH+H_2O

I need a balanced oxidation reaction and reduction reaction, please.

 

This is another equation: In(s) + Cr2O72−(aq) → In(OH)3(s) + Cr(OH)4(aq)

I need it balanced, and I also need a balanced oxidation reaction and the reduction reaction.
