In a reaction, 5.3g of sodium carbonate reacted with 6 g of acetic acid. The products were 2.2 g of carbon dioxide, 0.9 g water and 8.2 g of sodium acetate. Show that these observations are in agreement with the law of conservation of mass.
Sodium carbonate + acetic acid \(\rightarrow \) Sodium acetate + carbon dioxide + water

Sodium carbonate + Acetic acid \(\rightarrow \) Sodium acetate + Carbon dioxide + Water

(5.3g) + (6g) \(\rightarrow \) (8.2g) + (2.2g) + (0.9g)

\(\Rightarrow \) 11g = 11g

\(\Rightarrow \) LHS = RHS

\(\therefore \) Mass of reactant = Mass of product

which satisfies the law of conservation of mass.
