The lattice energy would need to be 4711 kJ for the formation of NaCl2 to be exothermic.
Iron is a metal and therefore is not made of molecules, but rather atoms. Molecules are only for covalent substances like sand, which is SiO2. No, they would not look the same if you could magnify them enough to see them. Metals form a "sea of electrons" with the inner shells of the atoms surrounded by delocalized electrons. SiO2 is a network solid which would have more of a lattice type structure. The size of the atoms would be different as well.
Inside one of the open spaces of an ice crystal, there are water molecules arranged in a lattice structure. These spaces are called "interstices" and they allow for the formation of a repeating pattern of hydrogen bonds between adjacent water molecules. The arrangement of the water molecules determines the shape and symmetry of the ice crystal.
Because iron is more reactive than copper. If iron displaces copper, that releases energy (enthalpy). If copper were to displace iron, that would require energy to be used. This is less favourable and , averaged over the huge number of molecules, atoms and ions in the solution, the more energy producing reaction is vastly preferred. Hence, iron put into copper sulphate solution gets coated in copper and the solution slowly loses its blue colour. But if you put copper metal in iron sulphate solution, nothing noticable occurs.
A chemical compound always consists of two or more elements combined together, and therefore molecules of at least two atoms. A substance which was only one element would simply be a sample of the element. There are some monoatomic elements, the noble gases, helium and group 18 neon argon etc.
It is a solid metal and therefore latice form.
the lattice surrounded his prey
Lattice is a pattern where pieces are interlaced. An example of a sentence with the word lattice in it would be, she decided to make a lattice crust on her cherry pie.

I think it would be a point defect because a vacancy in the lattice structure would allow another atom to take the place of the vacancy.

The chemical formula for copper sulphate is CuSO4. It contains:One copper atomOne sulphur atomFour oxygen atomsIn addition, the natural form of copper sulphate differs with its amount of water molecules. The most commonly encountered form is blue. Its chemical formula is CuSO4•5H2O. It contains: Copper sulphate (see above)Five water molecules, which contain: Two hydrogen atomsOne oxygen atom
Helium comes very close to ideal at STP since it is so small and monatomic. In reality most gases are pretty indistinguishable from ideal at STP because the molecules are so far apart that their individual volumes are negligible compared to the space they are in and the molecules are so far apart that they exert negligible force on each other.
You would get water in the gas phase (steam). The word "hydrated" means that there are water molecules mixed in with the copper sulphate, and so when you heat it, you will turn that water into steam, freeing it. Because of the high melting point of ionic compounds like copper sulphate, it will not be affected by heating unless you go to extemely high temperatures.
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
