Question

Take three test-tubes. Fill 3/4th of each with water. Label them A, B and
C. Keep a snail in test-tube A, a water plant in test-tube B and in a
keep snail and plant both. Which test-tube would have the highest
concentration of CO ? Test-tube C​

Answer 1

THREE SITUATIONS ARE PROVIDED-

1. Test tube A - Contains snail and water $(\frac{3}{4} )$

2. Test tube B- Contains Water plant and water.

3. Test tube C- Contains water, plant, and snail.

Snail- Produce CO in water

Water plant - Produce $O_{2}$ water

So we can infer from that information that test tube A contains the highest concentration of CO.

Hence, Test tube A has the highest concentration of CO.
