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.

Nonrenewable we only use them and renewable we can use them over and over.
Answer:
it will have 1 valence electron as its in the first group in the periodic table.
It will lose electrons as its easier.
The charge will be 1+ as it lost 1 .
