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.

D because 0 is always ignorant in significant figures. hope that helps:)
The word can be conclusion, but it can't be if the ''L'' is capitalized
The answer is d cuz it’s doesn’t make a lot of the formula
Explanation:
Alkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown color to give a colorless liquid. In the case of the reaction with ethene, 1,2-dibromoethane is formed.
