Question

law of conservation of mass questions 1. the masses of the reactants and products of the following reaction are given. answer the questions below. hcl + naoh → nacl + h₂o mass 36g + 40g → 58g + 18g iv) does this data verify the law of conservation of mass? if so, why?

Explanation:

Step1: Calculate total mass of reactants

Mass of HCl is 36g and mass of NaOH is 40g. So total mass of reactants = 36g + 40g = 76g.

Step2: Calculate total mass of products

Mass of NaCl is 58g and mass of H₂O is 18g. So total mass of products = 58g + 18g = 76g.

Step3: Compare reactants and products mass

Since total mass of reactants (76g) is equal to total mass of products (76g), the law of conservation of mass is verified. This law states that in a chemical reaction, the total mass of reactants is equal to the total mass of products as matter is neither created nor destroyed.

Answer:

Yes, the data verifies the law of conservation of mass. Because the total mass of reactants (36g + 40g = 76g) is equal to the total mass of products (58g + 18g = 76g), which is in accordance with the law of conservation of mass (mass is conserved in a chemical reaction, matter is neither created nor destroyed).
