Question

The number of terminal oxygen atoms present in the product B obtained from the following reactions is:

\[\ce{FeCr2O4 + Na2CO3 + O2 -> A + Fe2O3 + CO2}\]

\[\ce{A + H^+ -> B + H2O + Na^+}\]

विकल्प

• 2

• 4

• 6

• 8

Answer 1

6

Explanation:

\[\ce{FeCr2O4 + Na2CO3 + O2 -> \underset{(A)}{Na2CrO4} + Fe2O3 + CO2}\]

\[\ce{\underset{(A)}{Na2CrO4} + H^+ -> \underset{(B)}{Na2Cr2O7} + Na^+ + H2O}\]

The number of terminal oxygen atoms present in the product B is 6.
