Answer:
cylinder A has a higher density then cylinder B or more accurately the liquid in cylinder A is denser then the liquid in the second tube.
Explanation:
"Denser" simply means more matter is contained in the same space for example say you fill a tank with helium and another tank with water. Although they are the same size one will weigh much more because their is more particles or "stuff" inside the same area this can be because of a few things one it can be because the atoms or elements that compose the substance are heavier containing more electrons and protons in their orbit. or the molecular structure is more compact like a chicken wire fence has more wire in it then a barbed wire wire fence covering the same area because of the grid of wire in the middle.

Answer:
on N overlaps with 1s on H.
Explanation:
Hybridization of central atom generally can be found by finding the hybridization number.Hybridization number is the sum of number of lone pairs and number of sigma bonds.
If hybridization number is 2 then the central atom is sp hybridized.
If it is 3 it is 
hybridized.
If it is 4 it is hybridized and so on.
Here in 
molecule there are 3 sigma bonds and one lone pair(see the figure attached).
Hence hybridization number is 4 and hence it is s
hybridized.
And in case of hydrogen atom the only electron of it resides in the 1s orbital.
Therefore on N overlaps with 1s on H.
Answer:
Hydrogen bonds are totally different to both covalent bonds and ionic bonds. Hydrogen bonds are intermolecular bonds, that means they occur in between two molecules. ... When H atom is close to O,F, N atoms those atoms can attract H atoms electrons temporarily, thus making a weak bond.
