If 28.4 g of HgO decomposes and produces 2.0 g of oxygen, then 26 grams of Hg is produced.
<h3>What is decomposition reaction?</h3>Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.
There are three different kinds of breakdown reactions: thermal, photolytic, and electrolytic.
=
=
28g = + 2g
= 26g
Thus, 28.4 g of HgO decomposes and produces 2.0 g of oxygen, then 26 grams of Hg is produced.
X 100%
= 26g/28g
= 93%
thus 93% is the percent by mass of Hg present in HgO.

Answer:
The net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide is -470.4 kJ/mol.
Explanation:
Step 1 : Calcium carbide and water react to form acetylene and calcium hydroxide
..[1]
Step 2 : Acetylene, carbon dioxide and water react to form acrylic acid
..[2]
Using Hess's law:
[1] × 6 + [2]
The energy released on formation of 5 moles of acrylic acid = -2352 kJ
The energy released on formation of 1 moles of acrylic acid :
Hence, the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide is -470.4 kJ/mol.
