Question

Q.]When Solid mercury (II)oxide is heated, liquid mercury and oxygen gas are produced. write chemical equation for the following reaction

Answer 1

Explanation: When Mercury(II) oxide is heater, the products obtained are Mercury in its elemental state and oxygen gas.

The balanced chemical equation follows:

$2HgO(s)\xrightarrow[ ]{\Delta }2Hg(l)+O_2(g)$

By Stoichiometry,

2 moles of Mercury oxide decomposes to produce 2 moles of Mercury and 1 mole of oxygen gas.
