![**Question:**
When a piece of manganese metal is dropped in a solution of hydrochloric acid, bubbles form. What are the bubbles that formed?
**Choices:**
- ○ H₂O
- ○ CO₂
- ○ HCl
- ○ H₂
- ○ Manganese gas
- ○ None of these
**Explanation:**
In general chemical reactions between metals and acids, the metal displaces hydrogen from the acid, resulting in the release of hydrogen gas (H₂). When manganese reacts with hydrochloric acid, the following reaction takes place:
\[ \text{Mn} + 2\text{HCl} \rightarrow \text{MnCl}_2 + \text{H}_2 \]
Thus, the bubbles observed in this reaction are hydrogen gas (H₂) formed due to the displacement of hydrogen atoms from the acid by the manganese metal.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc4f0980f-8ca7-4285-9514-1d06b47f382d%2F1564b8a5-3270-4c17-ba02-804ebeb19a44%2Fd1cv2sd_processed.png&w=3840&q=75)
