Answer:
The given equation obey the law of conservation of mass.
Explanation:
Chemical equation:
2LiOH + CO₂  →   Li₂CO₃ + H₂O
There are equal number of atoms of oxygen, hydrogen and lithium on both side of equation so it obey the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
2LiOH                +            CO₂         →         Li₂CO₃           +                    H₂O
2(6.941 + 16 + 1)  +          12+32                   6.941×2 + 12 + 3×16     +       18
47.882 + 44                                                  13.882 +12+48   +   18
91.882 g                                                                91.882 g
The mass of reactants and product are equal.
