Answer:
ΔHf0=ΔHsub+IE+ΔHdiss+EA+U
ΔHf0=108+496+122−349−788=411kJ/mol
The enthalpy change in the formation of an ionic lattice from the gaseous isolated sodium and chloride ions is −788 kJ/mole. That enthalpy change, which corresponds to the reaction Na(g)+Cl(g)→NaCl(s), is called the lattice energy of the ionic crystal. Although the lattice energy is not directly measurable, there are various ways to estimate it from theoretical considerations and some experimental values. For all known ionic crystals, the lattice energy has a large negative value. It is ultimately the lattice energy of an ionic crystal which is responsible for the formation and stability of ionic crystal structures.
For sodium chloride, the Born

Answer:
Enantiomers
Chiral
Yes they will be formed in equal amount.
Explanation:
The Two possible stereo isomers are formed due to generation a chiral center in the molecule.
There will be a carbon with all the four groups different.
The two isomers will be called as enantiomers, which are non super-imposable mirror image of each other.
They are named as "R" or "S'" based on the selection rule.
The IUPAC names are also given in the figure.
The two isomers will be formed in equal amount as during photochemical chloriantion of a compound free radicals are generated (which are trigonal planar) and the other radical may attack from either side (front side or back side) giving the two stereo-isomers.
The correct term to fill in the blank would be decrease. Phytic acid, tannins, and oxalates decrease the absorption of many minerals. Phytic acid reduce the absorption of a number of minerals like iron, zinc and calcium. Also, it would encourage mineral deficiencies. The same is also true for tannins and oxalates.
