When hydrochloric acid reacts with sodium sulfide, hydrogen sulfide gas and sodium chloride are produced. How many moles of H2S
will be generated by 2.56 moles of HCl?
2HCl + Na2S → H2S + 2NaCl
1 answer:
Answer:
mol H2S = 1.28 mol
Explanation:
balanced reaction:
- 2HCl + Na2S → H2S + 2NaCl
∴ moles HCl = 2.56 mol
⇒ moles H2S = ?
⇒ moles H2S = (2.56 mol HCl)*(mol H2S/2 moles HCl)
⇒ moles H2S = 1.28 mol
