Final answer:
Amsorb contains calcium hydroxide and has the advantage of lesser reactivity with volatile anesthetic agents compared to soda lime, reducing the risk of undesirable byproducts.
Step-by-step explanation:
The question is regarding the components and advantages of Amsorb compared to soda lime when used in anesthetic gas removal systems. Amsorb and soda lime are both used in medical settings to absorb carbon dioxide (CO₂) during anesthesia. Soda lime typically contains calcium hydroxide while Amsorb does not contain silica or potassium hydroxide, which are present in soda lime, thus reducing the chances of the Compound A production when it reacts with anesthetic gases. One of the advantages of Amsorb over soda lime includes lesser reactivity with volatile anesthetic agents, which minimizes the risk of producing undesirable byproducts in the presence of carbon dioxide absorbing reactions. Therefore, the correct answer that describes Amsorb and its advantages over soda lime is "Calcium hydroxide; lesser reactivity" which corresponds to option A.
