Answer:
there are 18 electrons in the outermost shell of argon atom
Answer:
- 3.1 cm
- 14.1%
Explanation:
L.error = student's measurement - actual length
L.error = 23.1-20.0
= 3.1
the percentage is 3.1/22*100=14.1%
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.
The mass of the liquid is 280 g.
Mass = 200 mL × (1.4 g/1 mL) = 280 g
