Question

5.0 grams of sodium carbonate reacts with 16.0 gram of hydraulic acid, it results in the formation of 6.0 gram of carbon dioxide and 15.0 sodium chloride solution to the results for the laws of conservation of mass.

Answer 1

Answer:

naco3 + hcl ----> nacl + co2 + h2o

5gm. 16gm. 15gm. 6gm

hence w product = w reactant so it obey mass conservation law
