In a reaction, 5.3 g of sodium carbonate reacted with 6 g of ethanoic acid. The products were 2.2 g of carbon dioxide, 0.9 g of water, and 8.2 g of sodium ethanoate. Show that these observations are in agreement with the law of conservation of mass carbonate.
Sodium carbonate + Ethanoic acid $\rightarrow$ Sodium ethanoate + carbon oxide + water
5.3g + 6g $\rightarrow$ 8.2 g + 2.2 g + 0.9g
LHS = RHS
Therefore, 11.3g = 11.3g
(Mass of reactant) (Mass of product)
This shows that during a chemical reaction mass of reactant = mass of product.
