Question

In the reaction 2NaCl + 2H2O ? 2NaOH + Cl2 + H2, the reactants should:

1.) weigh more than the products because the 1.)reaction isn't perfect
2.) weigh less than the products because mass is lost
3.) weigh the same as the products
4.) weigh more because Cl2and H2are gases

Answer 1

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

Step-by-step explanation:

it was correct

Answer 2

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.
