Populations in the deep-sea vent ecosystem can get energy storage molecules without sunlight. Do you agree or disagree with this
1 answer:
Answer:
Agree
Explanation:
<em>The deep-sea vent ecosystem gets energy storage molecules without sunlight.</em> Life in the vent ecosystem relies on alternate energy through the use of hydrogen sulfide present in the water emanating from the vent.
The producers that form the basis of the food chain are bacteria that use the hydrogen sulfide to create energy-rich molecule in a process known as chemosynthesis.
The equation of the chemosynthesis is as below:

Explanation:
The limiting reactant is the reactant that gives the smaller amount of product.
Assemble all the data in one place, with molar masses above the formulas and masses below them.
M_r: 39.10 80.41 2.016
2K + 2HBr ⟶ 2KBr + H₂
m/g: 5.5 4.04
a) Limiting reactant
(i) Calculate the moles of each reactant
(ii) Calculate the moles of H₂ we can obtain from each reactant.
From K:
The molar ratio of H₂:K is 1:2.
From HBr:
The molar ratio of H₂:HBr is 3:2.
(iii) Identify the limiting reactant
HBr is the limiting reactant because it gives the smaller amount of NH₃.
b) Excess reactant
The excess reactant is K.
c) Mass of H₂
