The fusion of chromite ore with sodium carbonate in the presence of air leads to the formation of products (\mathrm{A}) and (\mathrm{B}) along with the evolution of (\mathrm{CO}}_{2}). The sum of spin-only magnetic moment values ofAandandBis ______ B.M. (Nearest integer) [Given atomic number : (\mathrm{C}: 6, Na\mathrm{Na}: 11, O\mathrm{O}: 8, Fe\mathrm{Fe}: 26, Cr\mathrm{Cr}: 24)]The fusion of chromite ore with sodium carbonate in the presence of air leads to the formation of products (A ) and (B)

Correct answer

0

Step-by-step solution

The fusion of chromite ore with sodium carbonate in the presence of air leads to the formation of products (A ) and (B)
Spin only magnetic moment For Na2CrO4μB=0\mathrm{Na}_2 \mathrm{CrO}_4 \quad \mu_{\mathrm{B}}=0 For Fe2O3μB=5.9\mathrm{Fe}_2 \mathrm{O}_3 \quad \mu_{\mathrm{B}}=5.9 sum =5.9=5.9
