Hi Steve,

How are you doing. First let me say thank you for answering my other question.

Could u please tell me how to balance the following redox equations.

I been trying to do them i dont' know if i am right or not. and for some i am getting

the electron on both side.

 

1. cu + NO3- ->  cu2+ + NO (acidic solution)

2.  MnO4- + ClO2- -> MnO2 +OH- + ClO4- (basic solution)

3. cr2O72- + C8H10 -> C7H6O2 + CO2 + Cr3+ (acidic solution)

4. NO3- + As2S3 -> AsO43- + SO42- + NO (acidic solution)

5. I2 +cl2 -> H3IO62- +Cl -

 

Thank you in advance.
