Question

NaClO+Cr2O3+NaOH=Na2CrO4+NaCl+H2O

Answer 1

Ответ:

3 NaClO  + Cr2O3  + 4 NaOH  → 2 Na2CrO4  + 3 NaCl  + 2 H2O

Cl(+1) + 2 e- → Cl(-1)   2   3

                                      6

Cr(+3) - 3 e- → Cr(+6) 3   2

Answer 2

The balanced chemical equation for the reaction you provided is:

3 NaClO + Cr2O3 + 6 NaOH → 2 Na2CrO4 + 3 NaCl + 3 H2O

In this reaction, sodium hypochlorite (NaClO) and chromium(III) oxide (Cr2O3) react with sodium hydroxide (NaOH) to produce sodium chromate (Na2CrO4), sodium chloride (NaCl), and water (H2O).

Please note that it's always important to double-check the coefficients and balance the equation to ensure accuracy.
