Question

Balance the following reaction: NaOH + HCl → NaCl + H2O Enter your answer in the space provided.

Answer 1

It's already balanced since there is an equal number of elements on each side!

I hope this helps!

Answer 2

The balanced reaction is NaOH + HCl ⇒ NaCl + H₂O

Step-by-step explanation:

One mole of sodium hydroxide reacts with one mole of hydrochloric acid to form one mole of sodium chloride and one mole of water.

If we check the reaction equation, we see that the amount of mass is equal in both members of the equation.

NaOH + HCl ⇒ NaCl + H₂O

NaOH= 22.99 g/mol + 15.99 g/mol + 1.007g/mol=39,987 g/mol

HCl= 1.007g/mol + 35,453 g/mol= 36.46 g/mol

NaCl= 22.99 g/mol + 35,453 g/mol= 58.443 g/mol

H₂O= 2×1.007g/mol + 15.99 g/mol= 18.004 g/mol

NaOH + HCl = 39,987 g/mol + 36.46 g/mol = 76.447 g/mol

NaCl + H₂O = 58.443 g/mol + 18.004 g/mol = 76.447 g/mol

Both sides of the equation are equal.
