Answer :
(A) The balanced molecular equation will be:
(B) The balanced molecular equation will be:
(C) The balanced molecular equation will be:
(D) The balanced molecular equation will be:
Explanation :
Molecular equation : It is defined as a balanced chemical equation where the ionic compounds are expressed in the form of molecules rather than component of ions.
Precipitation reaction : It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined.
The insoluble salt that settle down in the solution is known an precipitate.
Part A : potassium carbonate and lead(II) nitrate
The balanced molecular equation will be:
In this reaction, lead carbonate is an insoluble salt and potassium nitrate is a soluble solution.
Part B : lithium sulfate and lead(II) acetate
The balanced molecular equation will be:
In this reaction, lead sulfate is an insoluble salt and lithium acetate is a soluble solution.
Part C : copper(II) nitrate and sodium sulfide
The balanced molecular equation will be:
In this reaction, Cuprous sulfide is an insoluble salt and sodium nitrate is a soluble solution.
Part D : strontium nitrate and potassium iodide
The balanced molecular equation will be:
In this reaction, strontium iodide and potassium nitrate are soluble solution.
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.
