Answer:
2. Decreases
Explanation:
From the combined concept of entropy and the second law of thermodynamics, it can be concluded that during the positive change in entropy, the degree of randomness of a system increases.
But in case of photosynthesis, we see a negative entropy change because in the process of photosynthesis plants take disordered things as from the atmosphere and water from soil and finally make a highly ordered molecule Glucose, which is further used as a food product and source of energy by the plants. Thus it is clear that degree of randomness in decreasing in the process of photosynthesis and it is a negative change in entropy.

Answer:
<h2>0.62 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.62 moles</h3>
Hope this helps you
