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.
