Question
Chapter 4, Problem 3E
Interpretation Introduction
Interpretation:
The term “Chemical formula” is to be defined.
Concept Introduction:
A compound is represented by a chemical formula, which gives information about the elements present in that compound and the relative number of atoms contained in that compound.
In a compound, the atoms are contained in a fixed proportion, and to represent those proportions, a chemical formula is used.
