The chemical equation for this reaction is {eq}2LiOH + CO_2 \to Li_2CO_3 + H_2O Compound states [like (s) (aq) or (g)] are not required. The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. Enter either the number of moles or weight for one of the compounds to compute the rest. Some NASA spacecraft rely on this lithium hydroxide reaction to remove exhaled carbon dioxide from the air inside the spacecraft. All other trademarks and copyrights are the property of their respective owners. The balanced equation would be 2LiOH + CO2 --> Li2CO3 + H20.
