Question

1. the masses of the reactants and products of the following

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? ______
iii) are the two values the same? ______
iv) does this data verify the law of conservation of mass? if so, why?

Explanation:

i)

Step1: Identify reactant masses

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

Step2: Sum reactant masses

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

Step1: Identify product masses

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

Step2: Sum product masses

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

Compare reactant total (76g) and product total (76g).

Answer:

76g

ii)
