I think the correct answer from the choices listed above is option 3. In the reaction 2NaCl + 2H2O ? 2NaOH + Cl2 + H2, the reactants should weigh the same as the products. This is to agree with the law of conservation of mass where mass in should be equal to mass out.

Answer: the correct answer is the number 3... not the third one

Explanation:

it was correct
