MCQ
Which of the following does not give oxygen on heating ?
- A$K_2Cr_2O_7$
- ✓$(NH_4)_2Cr_2O_7$
- C$KClO_3$
- D$Zn(ClO_3)_2$
✓
Answer
Correct option: B.
$(NH_4)_2Cr_2O_7$
b
$\left(\mathrm{NH}_{4}\right)_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \stackrel{\Delta}{\longrightarrow} \mathrm{N}_{2}+\mathrm{Cr}_{2} \mathrm{O}_{3}+4 \mathrm{H}_{2} \mathrm{O}$ do not produces $\mathrm{O}_{2}$
$\left(\mathrm{NH}_{4}\right)_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \stackrel{\Delta}{\longrightarrow} \mathrm{N}_{2}+\mathrm{Cr}_{2} \mathrm{O}_{3}+4 \mathrm{H}_{2} \mathrm{O}$ do not produces $\mathrm{O}_{2}$
