Which is a molecular ion?
Correct answer: C. NH3+
- A. NH4+
- B. H3O+
- C. NH3+
- D. SO4 2-
Explanation
A molecule containing a positive or negative charge is known as a molecular ion. After hiding charge on an ion, if it looks independent individual molecule then it is called a molecular ion. If the positive charge on NH3+ is hidden by thumb then NH3+ is independent molecule of ammonia so it is a cationic molecular ion.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
