Question

K2Cr2O7+H2O+H2SO4=Cr2(SO4)3+O2+K2SO4 ОВР​

Answer 1

Объяснение:

2 K2Cr2O7 + 8 H2O + 8 H2SO4 → 2 Cr2(SO4)3 + 3 O2 + 2 K2SO4

4 CrVI + 12 e- → 4 CrIII

(восстановле́ние)

6 O-II - 12 e- → 6 O0

(окисление)

Answer 2

The balanced chemical equation for the reaction you mentioned is:

2 K2Cr2O7 + 8 H2SO4 + 3 H2O → 2 Cr2(SO4)3 + 7 O2 + 4 K2SO4

In this reaction, potassium dichromate (K2Cr2O7) reacts with water (H2O) and sulfuric acid (H2SO4) to produce chromium(III) sulfate (Cr2(SO4)3), oxygen gas (O2), and potassium sulfate (K2SO4).
