Expert Answer
Reaction of sodium carbonate reacted with ethanoic acid is,
Mass of sodium carbonate = 5.3 gm
Mass of ethanoic acid = 6 gm
Mass of Sodium ethanoate = 8.2 gm
Mass of carbon dioxide = 2.2 gm
Mass of water = 0.9 gm
Total mass of reactant = (5.3 + 6)
=11.3 gm
Total mass of products =( 8.2+2.2+0.9 )
= 11.3 gm
Total mass reactant = Total mass of products.
Therefore the observations are in agreement with law of conservation of mass.
