Using --> as a reaction arrow, please write the complete reaction and the net-ionic equation for the forth procedure:

 

**Chemical Reaction with Hydrochloric Acid and Zinc**

**Instructions:**

1. **Add Hydrochloric Acid:** Add 2 mL (40 drops) of 6 M hydrochloric acid (HCl) to the test tube.
   - **Safety Note:** CAUTION: HCl is corrosive. Keep it off your skin. If you spill acid on yourself, immediately flush the affected area with water for 2-3 minutes and notify your instructor.

2. **Introduce Zinc:** Drop one small piece of zinc into the test tube.

3. **Observe the Reaction:** 
   - When bubbling begins, hold an empty test tube over the mouth of the reaction tube.
   
4. **Test for Gas Production:**
   - After a minute, hold a glowing splint by the mouth of the empty test tube.
   
5. **Record Observations:** Record your observations for analysis and discussion.

**Explanation:**
- The hydrochloric acid reacts with zinc to produce hydrogen gas and zinc chloride. The bubbling observed is the hydrogen gas being released.
- Holding a glowing splint by the mouth of the empty test tube helps determine the presence of hydrogen gas. If the splint ignites with a pop sound, hydrogen gas is confirmed.

**Safety Reminder:** Always handle chemicals with care and follow lab safety protocols.
