#### Step 2: Match the Equipment to Columns
Using the identifications above, we can now match the equipment to the correct columns:

- Column A:
1. Erlenmeyer flask → Image 2
2. Corks → Not visible in the image (likely part of another item)
3. Pipette → Image 11
4. Beaker → Image 15
5. Spatula → Image 12
6. Test tube brush → Image 13
7. Bunsen burner → Image 20
8. Watch glass → Image 4
9. Mortar and pestle → Image 8
10. Dropper → Image 7
11. Funnel → Image 3
12. Balance → Image 19

- Column B:
1. Test tube holder → Not visible in the image (likely part of another item)
2. Wire gauze → Image 14
3. Ring stand → Image 17
4. Petri dish → Image 1
5. Hot plate → Image 21
6. Test tube rack → Image 5
7. Test tubes → Image 6
8. Thermometer → Image 10
9. Microscope → Image 16
10. Striker → Image 22
11. Graduated cylinders → Image 9
