Concept explainers

Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be ne…
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in t…
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the forma…

Chapter 1, Problem 1.76EP

(a)

Interpretation Introduction

Interpretation:

The chemical notation Hf is the chemical symbol for an element or a chemical formula of a compound has to be indicated and total number of atoms present in one formula unit of the substance has to be indicated.

Concept Introduction:

The composition of a chemical compound can be presented in a very precise was with the use of chemical formula.  Chemical formula uses chemical symbols of the elements that is present in the compound and numerical subscripts that represent how many number of atoms of each element is present in the compound.

Answer to Problem 1.76EP

Hf is chemical formula for an element and total number of atoms present is 1.

Explanation of Solution

Given chemical notation is Hf.  As there are only one atom present in the given chemical notation, it is a chemical formula of an element.

The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.

  Total No. of atoms = 1 Hf atom = 1 atom

Therefore, there is one atom in the given chemical formula.

(b)

Answer to Problem 1.76EP

HF is chemical formula for a compound and total number of atoms present is 2.

Explanation of Solution

Given chemical notation is HF.  As there are more than two elements present in the given chemical notation, it is a chemical formula of a compound.

The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.

  Total No. of atoms = 1 H atom   +    1  F  atom = 2 atoms

Therefore, there are two atoms in the given chemical formula.

(c)

Interpretation Introduction

Interpretation:

The chemical notation CoCl2 is the chemical symbol for an element or a chemical formula of a compound has to be indicated and total number of atoms present in one formula unit of the substance has to be indicated.

Concept Introduction:

Answer to Problem 1.76EP

CoCl2 is chemical formula for a compound and total number of atoms present is 3.

Explanation of Solution

Given chemical notation is CoCl2.  As there are more than one element present in the given chemical notation, it is a chemical formula of a compound.

The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.

  Total No. of atoms = 1 Co​ atom   +  2  Cl  atoms = 3 atoms

Therefore, there are three atoms in the given chemical formula.

(c)

Interpretation Introduction

Interpretation:

The chemical notation COCl2 is the chemical symbol for an element or a chemical formula of a compound has to be indicated and total number of atoms present in one formula unit of the substance has to be indicated.

Concept Introduction:

The composition of a chemical compound can be presented in a very precise was with the use of chemical formula.  Chemical formula uses chemical symbols of the elements that is present in the compound and numerical subscripts that represent how many number of atoms of each element is present in the compound.

Answer to Problem 1.76EP

COCl2 is chemical formula for a compound and total number of atoms present is 4.

Explanation of Solution

Given chemical notation is COCl2.  As there are more than one element present in the given chemical notation, it is a chemical formula of a compound.

The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.

  Total No. of atoms = 1 C​ atom  +  1  O atom  +  2  Cl  atoms = 4 atoms

Therefore, there are four atoms in the given chemical formula.
