Question

In a reaction, 4.0 g of sodium carbonate were reacted with 10g
of hydrochloric acid. The product was a mixture of 2.5g of carbon
dioxide and 11.5g of sodium chloride solution. Is this data in
agreement with the law of conservation of mass?​

Answer 1

Answer:

law of conservation of mass says that total.mass of reactant side should be equal to the total mass of product side ,

Explanation:

reactant side mass =4+0=14g

product side mass =2.5+11.5=14g

so it follows the law
