Overview

Chemical reactions are changes in which new substances are formed and the identity of the original substances changes. Common signs of a reaction include change in colour, change in state, evolution of gas, and change in temperature. Chemical equations give a short symbolic way to write reactions. A

Key Concepts

A chemical reaction forms new substances

A chemical reaction forms new substances from old ones. It is often noticed through colour change, gas formation, change in state, or temperature chan

A chemical equation is the symbolic

A chemical equation is the symbolic form of a reaction. Reactants are written on the left-hand side and products on the right-hand side. The arrow sho

A balanced equation has the same

A balanced equation has the same number of atoms of each element on both sides. This follows the law of conservation of mass, which says mass can neit

The symbols (s)

The symbols (s), (l), (g), and (aq) stand for solid, liquid, gas, and aqueous solution. Reaction conditions such as heat, sunlight, pressure, or catal

A combination reaction is one

A combination reaction is one in which two or more reactants form a single product. Many combination reactions release heat, so they are exothermic.

Learning Objectives

  • Identify signs that show a chemical reaction has taken place
  • Write word equations and chemical equations correctly
  • Balance chemical equations using the hit-and-trial method
  • Use state symbols such as (s), (l), (g), and (aq) in equations
  • Understand combination, decomposition, displacement, and double displacement reactions
