Question

Toppr Admin · Accepted Answer

The correct option is D HgO2HgOheat-x2212-x2212-x2192-2Hg-O2Reddish Mercuric oxide-II- solid is decomposed upon heating into silver liquid mercury and colourless oxygen gas-Since it is a decomposition reaction it breaks down the oxide into oxygen and the metal-

Which one of the following compounds gives oxygen on heating?
$Z n O$
$C u O$
${A l}_{2} O_{3}$
$H g O$

The correct option is D $H g O$
$2 H g O h e a t - - \to 2 H g + O_{2}$
Reddish Mercuric oxide(II) solid is decomposed upon heating into silver liquid mercury and colourless oxygen gas.
Since it is a decomposition reaction it breaks down the oxide into oxygen and the metal.

Which one of the following compounds gives oxygen on heating?ZnOCuOAl2O3HgO

The correct option is D HgO2HgOheat−−→2Hg+O2Reddish Mercuric oxide(II) solid is decomposed upon heating into silver liquid mercury and colourless oxygen gas.Since it is a decomposition reaction it breaks down the oxide into oxygen and the metal.
