Question

In a reaction, 4.0g 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.

Answer 1

Answer:

law of mass conservation is followed

Explanation:

The missing part of question statement is;

IS THIS DATA IN AGREEMENT WITH LAW OF CONSERVATION OF MASS?

Solution

Law of conservation of mass states that the mass of reactants taking part in the reaction must be equal to the mass of the products produced in reaction

Now in given case, Sodium carbonate and HCL are reactants and sodium chloride , carbon dioxide are the products.

Mass of reactants = 4g + 10g = 14g

Mass of products = 11.5g + 2.5g = 14 g

Since both the masses are equal, hence the law of mass conservation is followed

Answer 2

Answer:

14g

Explanation:

(step by step explanation)

The reaction is:

Sodium carbonate + hydrochloric acid = Sodium chloride + carbon dioxide

4g 10g 11.5g 2.5g

Mass of reaction = 4+10 = 14gm

Mass of reaction = 11.5+2.5 = 14gm

The mass of reactants is equal to the mass of the products. Therefore the given data

is in agreement with law of conservation of mass.

hope this helps
