In a chemical reaction of sodium carbonate (5.3g) and ethanoic acid (6 g) it forms (8.2g) sodium ethanoate, (2.2g) carbon dioxide and (0.9g) water.
Does this product formed follow the law of conservation of mass?

Sodium carbonate ethanoic acid -------> Sodium ethanoate carbon dioxide water
(5.3g) (6g) (8.2g) (2.2g) (0.9g)
5.3 g 6g ------> 8.2 g 2.2g 0.9g

Answer:
According to the question
Mass of reactants = 5.3 + 6 = 11.3 gm
Mass of products = 2.2 + 0.9 + 8.2 = 11.3 gm
This shows, that during a chemical reaction, the mass of reactant = mass of the product.
Hence, it shows the law of conservation of mass.
