Answer:
The structures are attached in file.
Hydrogen bonding and intermolecular forces is the reason for ranks allotted.
Explanation:
In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.
In order of decreasing affinity to water molecules:
This is due to the fact that the 
will accept protons more readily than the bicarbonate ion, 
. Carbonic acid, 
will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion. The gradient of the graph equals the density of the material.
Answer:
I don't know how to get the answer sorry

Answer:
Metallic Bonding. Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. ... That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
