Chapter 3.2, Problem 6RQ

(a)

Interpretation Introduction

Interpretation: Formula for the nitric acid needs to be determined.

Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 6RQ

The answer is nitric acid, ${\text{NHO}}_3$ .

Explanation of Solution

A notation to describe a substance that uses an atomic symbol and a numerical subscript to indicate the relative numbers of atoms (different elements in the substance) is defined as a chemical formula. In other words, chemical formulas are used to express chemical composition of substance. Chemical formula of any substance gives information elements that are included, number written in subscript represents the number of atoms/ molecules of that element.

A molecule containing one hydrogen atom, one nitrogen atom, and three oxygen atoms is nitric acid, ${\text{NHO}}_3$ .

(b)

Interpretation Introduction

Interpretation: The formula of compound listing hydrogen atom first needs to be determined.
