Question

10.6g of sodium cloride reacted with 7.3g of hydrochloric acid producing 11.7 g of sodium chloride, 1.8 g of water and 4.4 g of carbon dioxide gas. show that this data varifies the law of conservation of mass​

Answer 1

Answer:

According to the question,

Na

COONa

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.

Answer 2

Explanation:

Sol'n :

Sodium carbonate + hydrochloric acid > Sodium chloride + water + carbon dioxide gas

Mass of the react and reactants= 10.6+7.3=17.9g

Mass of the products= 11.7 + 1.8 + 4.4 = 17.9g

The mass of reactant= Mass of the product .

Hence,it shows the Law of conversation of mass.

Hope it helps you .
