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
i) what is the total mass of the reactants?

ii) what is the total mass of the products?

Explanation:

i)

Step1: Identify reactants' masses

Reactants are HCl (36g) and NaOH (40g).

Step2: Sum the masses

Total mass = 36g + 40g = 76g.

Step1: Identify products' masses

Products are NaCl (58g) and H₂O (18g).

Step2: Sum the masses

Total mass = 58g + 18g = 76g.

Answer:

76g

ii)
