Learn About Chemical Reactions

A chemical reaction is a process that transforms substances (reactants) into new substances (products) with different properties. During a reaction, bonds are broken and formed.

  • Synthesis (Combination) – A + B → AB
  • Decomposition – AB → A + B
  • Single Displacement – A + BC → AC + B
  • Double Displacement – AB + CD → AD + CB
  • Combustion – Hydrocarbon + O₂ → CO₂ + H₂O
  • Acid-Base Neutralization – Acid + Base → Salt + Water

Chemical equations must be balanced to satisfy the Law of Conservation of Mass. This means the same number of atoms of each element must appear on both sides of the equation.

Steps to balance:

  1. Write the unbalanced equation
  2. Count atoms on each side
  3. Use coefficients to balance atoms
  4. Check your work
