Place the coefficients in the following redox reactions HNO3 + FeO – Fe (NO3) 3 + NO + H2OK2MnO4 + H2O – MnO2 + KMnO4 + KOHCrCl3 + KNO3 + K2CO3 – K2CrO4 + CO2 + KNO2 + KClK2Cr2O7 + SnCl2 + KClK2Cr2O7 + SnCl4 + SnCl3 + H2O
10HNO3 + 3FeO = 3Fe(NO3)3 + NO + 5H2O
3K2MnO4 + 2H2O -> 2KMnO4 + MnO2 + 4KOH
2CrCl3 + 3KNO3 + 5K2CO3 = 2K2CrO4 + 3KNO2 + 5CO2 + 6KCl
3SnCl2 + K2Cr2O7 + 14HCl → 3SnCl4 + 2CrCl3 + 2KCl + 7H2O
