In a reaction 5.3 gram of sodium carbonate reacted with 6 team of ethanoic acid the product were 2.2 gram of carbon dioxide, 0.9 gram of water and 8.2 gram of sodium ethanoate show that these observations are in agreement with the law of conservation of mass. sodium carbonate + ethanoic acid gives sodium ethanoate+ carbon dioxide + water

Open in App

Solution

Total mass of reactants = mass of sodium carbonate + mass of ethanoic acid
= 5.3 g + 6 g= 11.3 g
Total mass of products = mass of sodium ethanoate + carbon dioxide + water
= 8.2 g + 2.2 g + 0.9 g = 11.3 g
Thus, the mass of reactants is equal to the mass of products, therefore the observations are in agreement with the law of conservation of mass.
