Sodium hydroxide (NaOH) and hydrochloric acid (HCl) combine to make table salt (NaCl) and water (H2O). Which equation is balanced?(1 point)

Question

Responses

2NaOH + HCl → NaCl + H2O
2NaOH + HCl → NaCl + H 2 O

2NaOH + 2HCl → 2NaCl + H2O
2NaOH + 2HCl → 2NaCl + H 2 O

NaOH + HCl → NaCl + H2O
NaOH + HCl → NaCl + H 2 O

NaOH + 2HCl → NaCl + H2O

Answer 1

The correct balanced equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) to form table salt (NaCl) and water (H2O) is:

NaOH + HCl → NaCl + H2O

This equation is balanced, as it has one sodium (Na), one chlorine (Cl), one hydrogen (H), and one oxygen (O) on both sides.

So the response with:

NaOH + HCl → NaCl + H2O

is the balanced equation.
