Question

Q6. State the Law of conservation of mass: Q7. Explain how photosynthesis demonstrates the Law of conservation of mas Explain using specific examples from the reaction.

Answer 1

6. The law of conservation of mass states that the matter can neither be created nor be destroyed which means that in a reaction the amount of reactant will be equal to the amount of product hence the mass of the system remain same over the time when nothing is added or removed externally.

7. The process of photosynthesis is a chemical reaction in which 6 molecule CO₂ reacts with 6 molecule of H₂O in the presence of sunlight to form 1 molecule of glucose and 6 molecule of O_2.

_{6CO2 6H2O CH12O+ 602}

As you can see in the reaction the mass of every element is same before and after the reaction, for example H have 12amu before and after the reaction.
