Question

The fusion of chromite ore with sodium carbonate in the presence of air leads to the formation of products A and B along with the evolution of CO2. The sum of spin-only magnetic moment values of A and B is ___ B.M. (Nearest integer) (Given atomic number : C : 6, Na : 11, O : 8, Fe : 26, Cr : 24]

Prashant Kotian · Accepted Answer

Correct answer: .. 4FeCr2O4 + 8Na2CO3 + 7O2 → 8Na2CrO4 + 2Fe2O3 + 8CO2 A B Spin only magnetic moment For Na2CrO4 µB = 0 For Fe2O3 µB = 5.9 sum = 5.9
