Question

A sample of water weed was placed in water and exposed to sunlight. Bubbles of a gas are seen on the surface of the leaves. (i) Name the gas evolved (ii) Name the process taking place (iii) Write a balanced equation of reaction taking place

Answer 1

 (i) Name the gas evolved
Carbon Dioxide

 (ii)Name the process taking placePhotosynthesis

(iii) Write a balanced equation of reaction taking place
6CO2 + 6H2O ------> C6H12O6 + 6O2. 

Answer 2

Answer:

(i) The gas that evolved is oxygen.

(ii) The process taking place in the given statement is photosynthesis.

(iii) 6CO₂+ 6H₂0→C₆H₁₂0₆ + 6O₂

Explanation:

• Photosynthesis is the process in which plants use carbon dioxide and water to form glucose in the presence of energy from the sunlight and release oxygen alongside the glucose molecule.
• 6CO₂+ 6H₂0→C₆H₁₂0₆ + 6O₂
• As the oxygen is evolved in the process, the bubbles of gas seen on the surface of leaves are of oxygen.
• Photosynthesis occurs in the plants having chloroplasts.
