Moderate alcohol consumption is no more than alcoholic drink(s) daily for adult women and up to
drink(s) daily for adult men.
What is an alcohol?
Alcohol is an organic compound containing a hydroxyl group and a carbon atom; Alcohol can be an intoxicant found in alcoholic beverages.
An alcoholic drink (also called an alcoholic beverage, adult beverage, or simply a drink) is a drink that contains ethanol, a type of alcohol that acts as a drug and is produced by fermentation of grains, fruits, or other sources of sugar.
The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages.
So, according to the scientific studies, the alcoholic consumption for women in a day is not more then one and for men is not for two drink(s)

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.
