Question

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

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

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

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

NaOH + HCl → NaCl + H2O

Answer 1

NaOH + HCl → NaCl + H2O

Check: Left — Na 1, O 1, H 2 (one in NaOH, one in HCl), Cl 1. Right — Na 1, Cl 1, O 1, H 2 (in H2O). All atoms balance.
