SMARTYK Class 10
Chemistry Notes Chapter: 1
Chemical Reactions And Equations
Concepts:
Chemical Reactions: A chemical reaction is the
transformation of a chemical substance into another
chemical substance. The substances that take part in a
chemical reaction are called reactants, and the new
substances produced as a result of the reaction are called
products.
Chemical Equations: A chemical equation concisely
represents a chemical reaction using chemical formulas
instead of words. The number of atoms of each element must
be the same before and after the chemical reaction, so the
chemical equations must be balanced.
Balancing Chemical Equations: Balancing a chemical
equation means making sure that the number of atoms of
each element is the same on both sides of the equation.
Types of Chemical Reactions: There are several types of
chemical reactions, including endothermic reactions,
exothermic reactions, combination reactions, decomposition
reactions, displacement reactions, and double displacement
reactions.
IMP POINTS: This chapter deals with chemical
reactions and equations in detail. In this chapter, we
will learn the basics of chemical reactions, their
types, and the effects of a chemical oxidation
reaction in our daily lives.
