What is the balanced chemical equation for the reaction between sodium sulfide (Na₂S) and hydrochloric acid (HCl)?
A. 2Na₂S + 2HCl → 2NaCl + H₂S
B. Na₂S + HCl → NaCl + H₂S
C. Na₂S + 2HCl → 2NaCl + H₂S
D. Na₂S + HCl → NaCl + 2H₂S
The balanced equation is 2Na₂S + 2HCl → 2NaCl + H₂S representing the reaction between sodium sulfide and hydrochloric acid.
