Answer:
When there is less carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available for producers making energy storage molecules. When there is more sunlight, producers can make more energy storage molecules from the carbon in carbon dioxide.
Hope this helps.
Oxygen because it is one the table of elements and none of the others are.
Answer:
Decreasing temperature.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- The choices here:
1) Decreasing concentration of SO₂,
The concentration of SO₂ decreases, so the reaction will be shifted to the left direction to suppress the decrease in SO₂ concentration.
2) Decreasing temperature,
ΔH= – 98.8 kJ/mol, the negative sign means that the reaction is exothermic and release the heat.
If the temperature decreased, this means that the products decrease, so the reaction will shift to the right to suppress the decrease in temperature.
<em>It is the right choice.</em>
3) Increasing concentration of SO₃:
Increasing concentration of SO₃ will shift the reaction to the left to suppress the effect of increasing the concentration of SO₃.
4) Increasing volume:
Increasing the volume will decrease the pressure.
Decreasing the pressure will shift the reaction of gases to the side of higher no. of moles (left side).
- <em>So, the right choice is: Decreasing temperature.</em>

The number of moles of iron produced can be obtained by the use of stoichiometry.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with mass - mole or mass - volume relationships. Stoichiometric relationships could be used to determine the amount of substance.
Now the reaction equation as well as other details are not shown in this question hence a numerical anwer can not be provided. As such, we can know that the balanced reaction equation can always be used to obtain the amount of iron by stoichiometry.
