Volume of carbon dioxide absorbed = 33.6 L ≈ 34 L
Explanation:
We have the following chemical reaction:
CO₂ (g) + 2 LiOH (s) → Li₂CO₃ (s) + H₂O (l)
Now we devise the following reasoning:
if 1 mole of carbon dioxide reacts with 2 moles of lithium hydroxide
then X moles of carbon dioxide reacts with 3 moles of lithium hydroxide
X = (1 × 3) / 2 = 3/2 moles of carbon dioxide
And we calculate the volume of carbon dioxide using the following formula:
number of moles = volume / 22.4
volume = number of moles × 22.4
note: units for 22.4 are "L / mole"
volume of carbon dioxide = (3/2) × 22.4 = 33.6 L ≈ 34 L

Answer:
Rabbit
Explanation:
I said rabbit because the snake feeds off the rabbit and that's where he gets his energy from. If the question asked you what is the primary source of energy in this food chain then the answer would be the sun. Since the question only asks you about the snake then the rabbit is the answer.
Hope this helps!
He was best known for the Continental Drift
Answer:
Generally, the first ionisation energy increases along a period. But there are some exceptions one which is not an exception
Answer: Extracellular [Ca2+]
Explanation:
The sensitivity and density of the alpha receptors serve to <em>enhance the response to the release of</em> <em>norepinephrine (NE)</em> . However, they do not exert a strong influence as the concentration of calcium ions on the amount of <em>norepinephrine (NE)</em> released by sympathic nerve terminals.
The release of neurotransmitters depends more on either an external or internal stimulus.This results in an action potential which on reaching a nerve terminal, results in the opening of Ca²⁺ channels in the neuronal membrane. Because the extracellular concentration of Ca²⁺ is greater than the intracellular Ca²⁺ concentration, Ca²⁺ flows into the nerve terminal. This triggers a series of events that cause the vesicles containing <em>norepinephrine (NE)</em> to fuse with the plasma membrane and release <em>norepinephrine (NE)</em> into the synapse. The higher the action potential, the higher the Ca²⁺ flow into the terminals resulting in higher amount of <em>norepinephrine (NE)</em> into the synapse, and vice versa.
Catechol-O-methyltransferase (COMT) is one of several enzymes that degrade catecholamines such as dopamine, epinephrine, and norepinephrine. It serves a regulatory purpose to lower the concentration of norepinephrine upon its release from nerve terminals.
