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
ii) partially visible
iii) are the two values the same? ____

Explanation:

Part (i) (assuming it's calculating total mass of reactants and products)

Step1: Calculate total mass of reactants

Reactants are HCl (36g) and NaOH (40g). So total mass of reactants = 36 + 40 = 76g.

Step2: Calculate total mass of products

Products are NaCl (58g) and H₂O (18g). So total mass of products = 58 + 18 = 76g.

Part (iii)

From part (i), total mass of reactants (76g) and total mass of products (76g) are equal. So the two values (mass of reactants and mass of products) are the same.

Answer:

(for iii):
Yes, the two values (total mass of reactants and total mass of products) are the same (both are 76g).
