How many moles of lithium hydroxide would be required to produce 35.0 g of Li₂CO₃ in the following chemical reaction? 2 LiOH(s) + CO₂ (g) → Li₂CO₃ (s) + H₂O (l)

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. [] → Ba(C1O₂)₂(aq) + H₂O(1) 2 X G
