Question

1. In a reaction, 5.3 g of sodium
carbonate reacted with 6 g of
acetic acid. The products were
2.2 g of carbon dioxide, 0.9 g
water and 8.2 g of sodium
acetate. Show that these obServations are agreement with law of conversations of mass .​

Answer 1

Answer:

Given, the reaction

sodium carbonate + acetic acid → sodium acetate + carbon dioxide + water

5.3g 6g 8.2g 2.2g 0.9g

Now,

Total Mass on the Left Hand Side = 5.3g + 6g = 11.3g

Total Mass on the Right Hand Side = 8.2g + 2.2g + 0.9g = 11.3g

As Mass on the LHS is equal to RHS, the observation is in agreement with the law of conservation of mass.
