Answer: Solid, liquid, and gas are the three phases of H2O that are listed in order of increasing entropy.
The haphazard motion of water molecules in molecular water gives it the maximum flexibility.
Answer:
See explanation.
Explanation:
A. 2s is incorrect, the right arrow should be pointing downwards.
B. In 2p, the last box has 3 arrows. This is invalid. Each box can only store 2 arrows(electrons). The last arrow should be moved to a 3p orbital (new box).
C. In this one, the arrows switched directions (left is down and right is up). You could fix each box or just the last one (in 3p) to point downwards.
Answer:
6.61 × 10∧-29 m³
Explanation:
Given data:
Atomic radius= 143 pm = 143 × 10∧-12 m
volume = ?
Formula:
r = a/2√2
143 × 10∧-12 m = a/ 2√2
a= 143 × 10∧-12 m × 2√2
a= 404.4 × 10∧-12 m
where a is edge length, so we can calculate the volume by using following formula:
volume= a³
V= (404.4 × 10∧-12 m)³
v= 6.61 × 10∧-29 m³
Answer:
fingerprint!
Explanation:
sounds cooler, and it should have fewer people in the category, making a higher chance if placing if you do it.
