MCQ
Which of the following does not give oxygen on heating ?
- ✓$(NH_4)_2Cr_2O_7$
- B$KClO_3$
- C$NaNO_3$
- D$K_2Cr_2O_7$
✓
Answer
Correct option: A.
$(NH_4)_2Cr_2O_7$
a
${\left( {N{H_4}} \right)_2}C{r_2}{O_7}\xrightarrow{\Delta }2N{H_3} + C{r_2}{O_3} + \frac{3}{2}{O_2} + {H_2}O$
${\left( {N{H_4}} \right)_2}C{r_2}{O_7}\xrightarrow{\Delta }2N{H_3} + C{r_2}{O_3} + \frac{3}{2}{O_2} + {H_2}O$
