Solution:

#### Step 1: Identify Each Equipment
We will go through each numbered item in the image and identify it along with its primary function.

---

#### Row 1:
1. Beaker
- Function: Used for holding, mixing, and heating liquids. It has a wide mouth for easy access and pouring.

2. Balance Scale
- Function: Used for measuring the mass of solid substances accurately.

3. Pipette (Bulb Pipette)
- Function: Used for transferring precise volumes of liquid from one container to another.

---

#### Row 2:
4. Round-Bottom Flask
- Function: Used for heating and reacting chemicals. Its rounded bottom prevents localized overheating.

5. Funnel
- Function: Used for transferring liquids or solids into narrow-mouthed containers without spilling.

6. Graduated Cylinder
- Function: Used for measuring precise volumes of liquids.

7. Test Tube Holder
- Function: Used to hold test tubes securely while heating them over a flame.

8. Spatula
- Function: Used for transferring small amounts of solid substances, such as powders or crystals.

---

#### Row 3:
9. Syringe
- Function: Used for drawing up and injecting precise volumes of liquids, often in experiments involving gases or liquids.

10. Burette
- Function: Used for titration experiments to deliver precise volumes of liquid drop by drop.

11. Ring Stand with Clamp
- Function: Used to support and hold laboratory glassware, such as flasks and beakers, during heating or other procedures.

12. Reagent Bottle
- Function: Used for storing and dispensing chemical reagents.

---

#### Row 4:
13. Rubber Stopper
- Function: Used to seal the openings of glassware to prevent contamination or loss of contents.

14. Triangle Support
- Function: Used to support a crucible or evaporating dish when heating substances over a flame.

15. Bunsen Burner
- Function: Used for providing a controlled flame for heating purposes.

16. Microscope
- Function: Used for magnifying and observing small objects, such as cells or microorganisms.
