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:
Multiple organisms may be affected by the loss of a plant species.
Explanation:
Organisms that feed directly off the lost plant will be affected, and because of that, organisms that feed off those organisms will be affected. This could also affect other organisms like parasites. Other plant species may be affected from the loss of a competitive species. This could affect organisms that feed off that plant, and the organisms that feed off those organisms.
Velocity is explained as the *speed and *direction something might move. Speed means moving and Direction means a certain way (not stationary.)
Hope this helps!
