, CHAPTER SOME BASIC CONCEPTS OF CHEMISTRY
1 STOICHIOMETRY-1
1. INTRODUCTION
Chemistry deals with the composition, structure and properties of matter. These aspects can be best de
scribed and understood in terms of basic constituents of matter: atoms and molecules. That is why chemistry
is called the science of atoms and molecules. Can we see, weigh and perceive these entities? Is it possible
to count the number of atoms and molecules in a given mass of matter and have a quantitative relationship
between the mass and number of these particles (atoms and molecules)? We will like to answer some of
these questions in this Unit. We would further describe how physical properties of matter can be quantita
tively described using numerical values with suitable units.
definite shape definite volume but no definite
& volume no definite shape shape & volume
fixed ratio of masses
of constituents
same composition throughout composition is
& component are indistinguishable. not uniform.
eg. gases, liquid solution, alloys, eg. sand & water,
atmospheric air nearly homogeneous
Consists of only one Made of two or more
type at atoms atoms of different elements
2. CLASSIFICATION OF UNIVERSE
Universe is classified into two types, matter and energy.
(A)MATTER : The thing which occupy space and having mass which can be felt by our five senses is called matter.
Matter is further classified into two categories :
(i) Physical classification (ii) Chemical classification
PHYSICAL CLASSIFICATION
It is based on physical state under ordinary conditions of temperature and pressure, so on the basis of two
nature of forces matter can be classified into the following three ways :
(a) Solid (b) Liquid (c) Gas
(a)Solid : A substance is said to be solid if it possesses a definite volume and a definite shape.
e.g. sugar, iron, gold, wood etc.
(b)Liquid : A substance is said to be liquid if it possesses a definite volume but not definite shape. They
take up the shape of the vessel in which they are put.
e.g. water, milk, oil, mercury, alcohol etc.
