In a reaction, 5.3 g of sodium carbonate reacted with 6 g of ethanoic acid.

Question.
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 water and 8.2 g of sodium ethanoate. Show that these observations are in agreement with the law of conservation of mass.

Solution:
Sodium carbonate reacts with ethanoic acid converted into sodium ethanoate, carbon dioxide,and water



$\therefore$ Total mass before the reaction $=$ Total mass after the reaction

Hence, the given observations are in agreement with the law of conservation of mass.
