It does not balance, in atomic terms. Some early spacecraft canisters used lithium hydroxide or hydrated lithium hydroxide instead of lithium peroxide, which would produce water: 2 LiOH + CO2 -> Li2CO3 + H2O or for hydrated lithium hydroxide: 2 LiOH.H2O + CO2 → Li2CO3 + 3 H2O Lithium hydroxide is still used in some other CO2-scrubbing-of-breathing-gas applications, eg scuba rebreathers and submarine emergency systems - but it isn't often used in spacecraft nowadays, lithium peroxide is generally preferred. -- Peter Fairbrother
