Question

Lithium hydroxide may be used to absorb carbon dioxide in enclosed environments, such as manned spacecraft and submarines. Write an equation for the reaction that involves 2 mol of LiOH per 1 mol of CO₂. (Hint: Water is one of the products.)

a) 2LiOH(aq) + CO₂(g) → Li₂CO₃(aq) + H₂O(l)
b) LiOH(aq) + CO₂(g) → Li₂CO₃(aq) + H₂O(l)
c) LiOH(aq) + 2CO₂(g) → Li₂CO₃(aq) + 2H₂O(l)
d) 2LiOH(aq) + 2CO₂(g) → 2Li₂CO₃(aq) + 2H₂O(l)

Answer 1

Two moles of lithium hydroxide (LiOH) react with one mole of carbon dioxide (CO₂) to produce lithium carbonate (Li₂CO₃) and water (H₂O), as expressed in the balanced chemical equation provided. Option a

Step-by-step explanation:

The chemical reaction between lithium hydroxide (LiOH) and carbon dioxide (CO₂) in enclosed environments, like manned spacecraft and submarines, can be represented by the following equation:

2LiOH(aq) + CO₂(g) → Li₂CO₃(aq) + H₂O(l)

This reaction depicts the use of two moles of LiOH for every mole of CO₂. Water (H₂O) is produced as a by-product of this neutralization reaction. The product of this reaction is lithium carbonate (Li₂CO₃), which is soluble in water and does not precipitate in an aqueous solution. Option a
