Molecular formula of ascorbic acid is
Molar mass of ascorbic acid =
Converting 500.0 mg of ascorbic acid to moles: We use molar mass of ascorbic acid to convert mass to moles.
Converting 500.0 mg of ascorbic acid to molecules: The conversion factor used is 1 mole =
Answer:
the movement of carbon through the biosphere
Explanation:
Carbon cycle is one of the major biogeochemical cycles that occurs on Earth. It is the process whereby carbon moves or circulates throughout the earth. Carbon, which is a major component of many biological substances moves to and fro living organisms and the atmosphere in different forms.
Carbon is released and absorbed in different forms in the atmosphere. For example, carbon in form of carbondioxide (CO2) is released into the atmosphere by living organisms via the process of CELLULAR RESPIRATION. The CO2 is then absorbed by green plants for the process of PHOTOSYNTHESIS. The carbon is released back into the earth when decomposers degrade dead organisms. This process of recycling carbon via natural processes is called CARBON CYCLE.
Hence, the movement of carbon through the biosphere is the best description of carbon cycle in this question.
All options are as follow,
<span>A. PbS + O2→ PbO + SO</span>₂<span>
B. PbS + 2O</span>₂<span>→ PbO + 2SO</span>₂<span>
C. 2PbS + 2O</span>₂<span>→ 2PbO + 2SO</span>₂<span>
D. 2PbS + 3O</span>₂<span>→ 2PbO + 2SO</span>₂<span>
E. 3PbS + 3O2→ 2PbO + 2SO2
Option A is not balanced because the number of oxygen atoms are greater at right hand side.
</span><span>
Option B is not balanced because the number of oxygen are less at right hand side and number of sulfur atoms are greater at right hand side.
Option C is not balanced because the number of oxygen atoms are greater at right hand side.
Option D is Balanced, all elements are balanced at both sides.
Option E is not balanced because number of Lead and Sulfur atoms are greater at right hand side.
Result:
Equation in Option D is balanced and correct answer.
