Lithium oxide \( \left(\mathrm{Li}_{2} \mathrm{O}\right. \); molar ...
Lithium oxide \( \left(\mathrm{Li}_{2} \mathrm{O}\right. \); molar mass \( \left.=30 \mathrm{~g} \mathrm{~mol}^{-1}\right) \) is used in space shuttles to remove water vapour according to the following reaction
\( \mathrm{P} \) \( \mathrm{Li}_{2} \mathrm{O}_{(\mathrm{s})}+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightarrow 2 \mathrm{LiOH}_{(\mathrm{s})} \)
W If \( 60 \mathrm{~kg} \) of water and \( 45 \mathrm{~kg} \) of \( \mathrm{Li}_{2} \mathrm{O} \) are present in a shuttle
I. water will be removed completely
II. \( \mathrm{Li}_{2} \mathrm{O} \) will be the limiting reagent
III. \( 100 \mathrm{~kg} \) of \( \mathrm{Li}_{2} \mathrm{O} \) will be required to completely remove the water present
IV. \( 27 \mathrm{~kg} \) of water will remain in the shuttle at the end of the reaction
(A) II only
(B) II and IV
(C) III and IV
(D) II and III
