Sharing of 4 electrons between two atoms results in two double bonds. This can be see in the case of oxygen molecule (O2)
Atomic number of O = 8
Electron configuration of O = 1s²2s²2p⁴
Valence electron configuration: 2s²2p⁴
When 2 O atoms combine they share 4 electrons to form 2 double bonds. In addition, there are two lone pairs on each O atom.
Structural formula: O=O
Answer:
Yes, you would consider the mass × gravity at the centre of gravity of the object in question to cause a moment, hence it should be included in your resolution
You would also have to eat right lol
Answer:
Transferred material is in the same relative position on the disk as on the original sample
Explanation:
The usefulness of blotting techniques in molecular biology is that transferred material is in the same relative position on the disk as on the original sample
first we make a U turn and travel towards home in t = 20 s
so the distance of home from initial position is


Now after picking up the book we travel back with speed 20 m/s
so again after t = 20 s the displacement is given as

so the net displacement is given as


so it will be displaced by total displacement 200 m
