Chemical Reactions and Equations

Vocabulary flashcards covering key concepts from Chapter 1 of Class 10 Science about Chemical Reactions and Equations.

Chemical Reaction

A process in which substances change into new substances.

Chemical Equation

Representation of a reaction using symbols and formulas.

Balanced Equation

Number of atoms must be equal on both sides.

Combination Reaction

A reaction where two substances (A and B) combine to form one product (AB).

Decomposition Reaction

A reaction where one substance (AB) breaks down into two or more products (A and B).

Displacement Reaction

A reaction in which one element (A) displaces another element (B) in a compound (BC) to form a new compound (AC).

Double Displacement Reaction

A reaction involving two compounds (AB and CD) that exchange components to form two new compounds (AD and CB).

Oxidation

The gain of oxygen in a reaction.

Reduction

The loss of oxygen in a reaction.

Rusting

A process where iron reacts with air and moisture to form rust.
