Homework Answers
Answer -
A molecular equation is the balanced chemical equation in all the species are expressed as molecules (Not ionic compounds).
Option A - In this all the compounds are molecules. There is no ionic compounds in the equation. So, it is a MOLECULAR EQUATION
Option B - Ionic compounds (like H+,Cl-, etc)are present in the equation. So, it is a NOT a molecular equation.
Option C - In this all the compounds are molecules. There is no ionic compounds in the equation. So, it is a MOLECULAR EQUATION
Option D - Ionic compounds (like Na+,Cl-, Ag+ etc)are present in the equation. So, it is a NOT a molecular equation.
So, OPTION A and OPTION C are correct.
