MCQ
Oxygen gas is not produced from the following decomposition reaction
- A${K_2}C{r_2}{O_7}\,\xrightarrow{\Delta }$
- ✓$A{g_2}C_2O_4\,\xrightarrow{\Delta }$
- C$Pb{(N{O_3})_2}\,\xrightarrow{\Delta }$
- D$A{g_2}C{O_3}\,\xrightarrow{\Delta }$
$A{g_2}{C_2}{O_4}\xrightarrow{\Delta }2Ag + 2C{O_2}$
$pb{(N{O_3})_2}\xrightarrow{\Delta }pbO + 2N{O_2} + \frac{1}{2}{O_2}$
$A{g_2}C{O_3}\xrightarrow{\Delta }2Ag + C{O_2} + \frac{1}{2}{O_2}$
