MCQ
Compound which on heating produces paramagnetic acidic gas?
- ✓$Mg(NO_3)_2$
- B$Fe_2(SO_4)_3$
- C$FeCO_3$
- D$HgC_2O_4$
✓
Answer
Correct option: A.
$Mg(NO_3)_2$
a
$(a)\,\,Mg{(N{O_3})_2}\xrightarrow{\Delta }MgO + \mathop {N{O_2} \uparrow }\limits_{(Paramagnetic)} + {O_2} \uparrow $
$(a)\,\,Mg{(N{O_3})_2}\xrightarrow{\Delta }MgO + \mathop {N{O_2} \uparrow }\limits_{(Paramagnetic)} + {O_2} \uparrow $
$(b)\,\,F{e_2}{(S{O_4})_3}\xrightarrow{\Delta }F{e_2}{O_3} + S{O_3} \uparrow $
$(c)\,FeC{O_3}\xrightarrow{\Delta }FeO + C{O_2} \uparrow $
$(d)\,\,Hg{C_2}{O_4}\xrightarrow{\Delta }Hg + CO \uparrow + C{O_2} \uparrow + \frac{1}{2}{O_2} \uparrow $
