Question

. Given the reaction 2HgO → 2Hg + O2 , how many moles of elemental mercury will be obtained by the decomposition of 1 mole of HgO?

Answer 1

For the balanced chemical reaction, the decomposition of 1 mole of mercury(II) oxide (HgO) will produce 1 mole of elemental mercury.

Step-by-step explanation:

The question at hand involves the decomposition of mercury(II) oxide (HgO) to produce elemental mercury and oxygen gas according to the chemical equation 2HgO → 2Hg + O2. To determine the moles of elemental mercury produced from the decomposition of 1 mole of HgO, we refer to the stoichiometry of the balanced chemical equation. For every 2 moles of HgO that decompose, 2 moles of Hg are formed. Therefore, the decomposition of 1 mole of HgO will result in the production of 1 mole of elemental mercury.

Answer 2

one mole of HgO will give one mole of Hg.

Step-by-step explanation:

Given data:

Moles of HgO = 1 mol

Moles of Hg = ?

Solution:

Chemical equation:

2HgO → 2Hg + O₂

Now we will compare the moles of Hg with HgO from balance chemical equation.

HgO : Hg

2 : 2

1 : 2/2×1 = 1 mol

So, one mole of HgO will give one mole of Hg.
