Are these reactions redox or not? Indicate the oxidizing agent and the reducing agent, make an electronic balance
Are these reactions redox or not? Indicate the oxidizing agent and the reducing agent, make an electronic balance. Arrange the odds. a) NH3 + SO2 → N2 + S + H2O b) NH3 + HCl → NH4Cl c) Zn + HNO3 (conc.) → Zn (NO3) 2 + NO2 + H2O d) ZnSO4 + BaCl2 → Ba SO4 + Zn Cl2
a) is an OВР;
N (3-) H (+) 3 + S (4+) O (2-) 2 => N (0) 2 + S (0) + H (+) 2O (2-);
reducing agent – 2N (3-) – 6e -> N (0) 2 | 2 – oxidation;
oxidizing agent – S (4+) + 4e -> S (0) | 3 – recovery;
4NH3 + 3SO2 => 2N2 + 3S + 6H2O;
b) is not an OВР;
N (3-) H (+) 3 + H (+) Cl (-) => N (3-) H (+) 4Cl (-);
c) is an OВР;
Zn (0) + H (+) N (5+) O (2-) 3 (conc.) => Zn (2 +) (N (5+) O (2-) 3) 2 + N (4+ ) O (2-) 2 + H (+) 2O (2-);
reducing agent – Zn (0) – 2e -> Zn (2+) | 1 – oxidation;
oxidizing agent – N (5+) + 1e -> N (4+) | 2 – recovery;
Zn + 4HNO3 (conc.) => Zn (NO3) 2 + 2NO2 + 2H2O;
d) is not an OВР;
Zn (2+) S (6+) O (2-) 4 + Ba (2+) Cl (-) 2 => Ba (2+) S (6+) O (2-) 4 + Zn (2+ ) Cl (-) 2.
