Equalize the reactions by the electronic balance method, determine the oxidizing and reducing agents, their oxidation states, arrange the coefficients: Cu2S + KClO3 → CuO + SO2 + KCl
3Cu2S + 4KClO3 = 6CuO + 3SO2 + 4KCl.
6 | Cu (+1) – 1 e- → Cu (+2) (oxidation)
1 | S (-2) – 6 e- → S (+4) (oxidation)
1 | Cl (+5) + 6 e- → Cl (-1) (reduction)
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
