ICSE Class 10 Chemistry
Chapter: Chemical Reactions
A chemical reaction is a process in which one or more substances are converted into new
substances with different properties.
Characteristics of Chemical Reactions
• Evolution of gas
• Change in colour
• Formation of precipitate
• Change in temperature
• Change in state
Chemical Equations
A chemical equation represents a chemical reaction using symbols and formulae. Balanced
equations obey the law of conservation of mass.
